I think what you could do is kidnap him and raise him differently maybe in the US, but then again look what happened with baby Hillary. I think evil is inherent, it wouldn’t matter how you raise someone like that who is intrinsically viciously horribly evil. I think Hitlers father was very abusive but look at people like Jeffrey Dahmer and Hillary, they both raised in nice families but both grew up to be monsters.
Really I despise Hillary, she is nothing but a crook, but to compare her to Dahmer and Hitler is a bit of a stretch.
I don’t know about their families, but my impression is they might not have had the best families, but none of these 3 had the worst.
