Just to get one thing straight before I start. I'm using the common theistic definition of god as a being who created everything and is omnipotent, omniscient and omnibenevolent. So, when I say "god" or "good god" I'm referring to the concept of a god I just defined, not an abstract deistic or a pantheistic god.
1) God's lack of reaction to evil - Some people try to argue that god should remove evil in the world and complain about god's absence of action during horrible acts throughout human history. However, even though the reasoning in those arguments is correct, it's based on false premises - that a good god would PURPOSELY create evil and let it occur in the world. I intend to go to the root of the problem - Why would a good god create evil in the first place?
2) A good god wouldn't create evil - A god is omnipotent, therefore he is capable of creating a world without evil. He is omnibenevolent, therefore he wishes to create a world with maximal goodness. And he is omniscient(which is a little redundant considering he already has omnipotence) so he knows how to realize his plans. Evil and good are reversely proportionate -> The less evil there is in the world the more good there is in the world. If there is no evil in the world then there is a maximal amount of goodness in the world. Therefore, a god would strive to creating a world with maximal goodness and no evil.
Just consider this and tell me which god is the better one: a)god X creates a world A which is maximal in goodness. No living being ever suffers and everybody and everything lives in perfect harmony without ever hurting each other. Like an utopia we humans(or at least I) strive towards so much. God doesn't require of us to be irrational and have faith(belief without evidence) and instead interacts with humans daily, helps them and provides divine guidance to our race. Now, THAT sounds like a good god.
b)god Y creates a world B full of suffering. Now I'm talking about our world, earth. Billions and billions of living beings suffered, enduring agonizing pain and dying in various brutal ways. Thousands of people die of hunger and horrible diseases, people are getting shot, raped and beaten to death every day. And what about carnivores? Seriously, an organism (supposedly) designed purely for BRUTALLY KILLING others? If predator doesn't catchy it's prey, the predator dies of starvation. If predator catches its prey, the prey dies an agonizing and frightening death. Not to mention how much I could write about all the various nasty diseases. Ever heard of smallpox and black plague? What kind of a SICK, SADISTIC designer would design something like that? And what about natural disasters? Tornados, earthquakes, volcano eruptions, floods, tsunamis etc. Such phenomenons wouldn't happen in a perfectly designed earth, now would it? That means that god either: 1) Couldn't have made it better(not omnipotent and omniscient), 2) Didn't want to make it better(not omnibenevolent) and 3) Maybe, just MAYBE... god doesn't exist

I think I'm justified in saying that god X is better than god Y, am I not? Apparently not, according to some believers. I'm anticipating that many of you will say "YOU FORGOT ABOUT FREE WILL". No I didn't. In my experience it's the most frequent argument used against problem of evil and it fails for numerous reasons, first of all it doesn't even address all evil, it just TRIES to address evil from humans. I'll divide evils in 2 categories:
1) Evils in nature. Mostly what I described in b). Natural disasters and diseases. Your free will argument doesn't touch on those, so even if free will was a valid argument(and it's NOT), the problem of evil still wouldn't be solved since you have to account for a supposedly good god creating such monstrosities. In fact, I have never even heard of a good argument against natural evils and most believers would either stop arguing with me or completely ignore my points about them. I remember once when a guy attempted to justify natural disasters and diseases by saying god has a plan for us. Do I even need to explain why that is an invalid argument?
2) Evils occuring as a result of human nature. Here is where believers try to explain everything away by free will... and they fail.
REFUTATION OF FREE WILL ARGUMENT
1) Free will is an illusion. I can't really DO what I WANT, I don't even have the free will to CONTROL what I WANT. Example for the former: I can't survive without nutrition. Example for the latter: I'm a male and I can't want to have sex with another man since I'm not biologically determined to be homosexual.
We humans are simply acting according to our DNA, brain and chemical reactions in it. Who (supposedly) designed them? God. So, god is ultimately responsible for whatever we do since he supposedly designed us. And since he is omniscient and omnipotent he could have designed us any way he wanted and he knows what the repercussions will be of any particular type of design and knows what we will do before us.
We are limited by natural laws, state laws and even our own mind and imagination.
2) Free will, evil and morality. - A good god wouldn't create beings wanting to do evil. Besides, god supposedly already made a lot of limitations already(as I listed above) so I don't see why wouldn't he make a POSITIVE limitation and remove some of the NEGATIVE ones. Removing evil from mankind would be a POSITIVE limitation. Even us humans are moral and rational enough to determine that absolute freedom is negative for the society and that we need limitations(LAWS) and that an individual is free as long as he doesn't hurt others(do evil). Not only is wanting to do evil unnecessary in being a moral agent and a free person, it's UNWANTED since us moral humans DON'T WANT others to want to do harm and evil, even at the expense of their freedom (prisons). So why doesn't god realize that and remove evil from mankind? Why didn't god make us FREE FROM EVIL? God could have given us the ability to make choices but between good choices, not good and bad choices.
I'll try to illustrate another point with the following question:
If you see a pedophile trying to rape a child would you: A) Stop him from hurting the child or B) Say: "Oh well, it's your free will to rape that child and I can't interfere with other people's free will, so go ahead".
I assume that you would do A. So why does god do B? What kind of a sadistic, perverse, psychopath monster creates a psychopath and then lets it rape a child, CARING MORE ABOUT THE PEDOPHILE'S FREE WILL THAN THE VICTIM'S?
3) Heaven and hell, concerning free will. This argument only applies to those who believe in heaven and hell, the rest can skip it
So, a presumably good god creates evil beings in a world full of evil and lets them do evil to innocent, good beings. He thinks that somehow a world WITH evil is BETTER than a world without. Or does he?
Do we have free will in heaven and hell? The answer for hell is an obvious NO. Setting aside the ridiculous concept of hell, an infinite punishment by torture for a finite sin which ultimately won't benefit anybody since the victim will be tortured forever AGAINST HIS FREE WILL in god's personal torture chamber I'll mostly focus on heaven.
Assuming that in heaven nobody ever does anything evil, do we have free will in heaven? Pick: A) No - We lose our free will in heaven or B) Yes, free will can be had without ever doing evil.
Also, if there is a heaven what's the point of this life? In comparison to heaven this life seems pointless. There's no reason to live in an imperfect world full of evil and suffering if you can live in a perfect world full of goodness. So why wouldn't everybody just suicide and go to heaven? Though if heaven really existed you wouldn't even call it "death" and "suicide", but transcendence to a higher, better reality. And since god is supposedly good I'm sure he wouldn't mind us avoiding unnecessary suffering. So why don't we massively commit suicides?
Simply, because we know that this life is the only one we have and that heaven doesn't exist and that's a proven scientific fact (psychology, brain biology anyone?). About as certain as gravity. Most people know that on a subconscious level anyway, and that's why they don't commit suicide and are still afraid of death and mourn their loved ones when they die.

I'm not completely finished yet, I will also formulate some of my arguments in form of a deductive logical argument when I find some more time.
Sorry for the long post and thanks for reading this far
