I must admit, the contents of the posts on this subject have made me think - which, after all, is why we are here.
Jewscout; I do think (I have said this before, in another thread) that we should 'love' people like Hitler - loathsome as that sounds. religious beliefs, to my way of thinking, are the beliefs that would include a 'Now, What would God do here, in this case' scenario. I think there is little doubt that God would love him - even if he is/was a very bad child. I struggle with this, because I cannot imagine myself loving Hitler - whatever my mind and my learning says, my emotions would come up, and make me want to do something horrific to him.
And there's the rub - "and make me want to do something horrific to him." - I would then be descending to his level, and doing something evil.
It does depend totally on the individual, which path he takes, at any one point; an abused person can either turn into an abuser, or can help other abused people recover from their problems. That would seem to indicate that evil is not an 'inherent' trait; I suppose I shaall have to disagree with Feathers, reluctantly, and say that we all have the ability to be good or evil.
