1. The killing of humans [especially impulsively and arbitrary] is a moral issue.
No. it's not - unless we assume (in this case) moral wrongness. So this premise begs the question.
2. Malignant psychopaths who kill humans [immoral] on impulse has some sort of damaged or abnormal brain the the majority.
This is a factual assertion with a truth-value, but no moral entailment.
3. Scientists had linked psychopathy its basis to the neural set up in the physical brain, thus this objective.
Ditto the above.
4. When the problem of malignant psychopathy is cured, correspondingly we would have resolved a moral issue re killing of humans.
Question-begging, as in 1.
5. In this specific case, morality is objective.
Bollocks. You don't understand the how a deductive argument works. I recommend a logic 101 course or simple text. Here's your invalid and unsound argument.
P1 X is a moral issue.
P2 To reduce the incidence of X is to resolve this moral issue.
C Therefore, in the case of X, morality is objective.
The missing moral premise is: X is morally wrong/bad/wicked. And the fact that you offer this ridiculous argument demonstrates your philosophical and logical incompetence.
