Morally responsible to who?
It is likely you are caught in the very common pseudo-sense of vulgar-morality where you can be held to be morally responsible to others. That is not what is morality-proper is about.
In morality-proper you are only held morally responsible to yourself and never to any others nor authorities.
If you are responsible to any authority, that would be politics [laws] and that is independent of morality-proper. It is the same with rules of any group - that is not morality-proper.
In morality-proper, the moral standards [justified true moral facts] are inherent within your own brain/mind and it is natural to align and flow with them spontaneously.
In this case, one has to activate one's moral function and moral competence continuously and progressively.
In a way, within natural morality-proper each of individuals are their own legislature, police, prosecutor, jury, and judge to facilitate your own moral progress.
The collective will facilitate and assist in the above.
The above is a totally contrasting paradigm to what the majority understood as 'what is morality' which is vulgar-morality and which in a way was corrupted by Hume.
As such it would be a good idea to research into the history of the subject of morality since Hume or prior?
Else the vulgar-moralists will keep talking pass those whose views are of morality-proper - till the cows come home.
That's 'Vulgar'-Morality versus Morality-Proper.
