Darwin posited a theory, nothing more.
Men are responsible for the evil men do.
The folks on this thread are positing a theory of their own, that is basically a variant “demon theology” - a bizarre and corrupt religious view that people are good, it is demons that cause them to do bad things - get rid of the demons and all is well.
That way the evil that men do isn’t their fault it was “demons”
Darwin’s Theory of Evolution is neither good nor bad in itself, it’s the faulty theology that evil comes from some external force to corrupt a “basically good” man created in God’s image - and then letting men assign who or what constitutes and “evil force” that is the whole root of this argument.
Fortunately we have lots of help on this thread - people that are of such stunning virtue, rivaled, maybe, only by Jesus Himself, who can tell the rest of us that THEY are the ones who know who and what is evil and what we should do about it.
