Op is rather silly.
He think that killing people is wrong even if evidence prove otherwise, but if all evidence prove that killing 100 sodomites save 1000 people from dying from AIDS, then he have to agree this is a good thing.
So if he believe killing is bad even if evidence shows it saves more lives, then he is just believing it based on faith and denying evidence.
Plus he be rather silly, he presume that if a devil or adversary was crafty and cunning, that the devil would be easy to "see" doing things behind the scenes.
That of course be rather silly, since that be like saying "I never saw Hitler personally kill Jews with his own hands, so HItler didn't organize the Holocaust".

So no, is actually plainly obvious that the Devil as described in the Bible is responsible for most of death and ill in humanity - if devil advocating sodomy or diseased lifestyles, then this lead to the majority of human deaths and suffering in recorded history, since disease has been biggest killer of humans, rather than weapons. This be why most sodomites die of aids rather than executions.
If Levitical God for example, advocate capital punishment for sodomites, then this be altruistic and save more lives by preventing spread of disease which would otherwise kill thousands or millions.
