where lex get his hate from

I'd say part of what he said was for show to manipulate everyone in disliking superman, tho he does think about the what if of superman getting evil and took it to an extreme and he does still seem to have a grudge on the whole amazo tech thing too. I think this take on lex will also be quite petty, and he's not the only lex who got the miltary in his pocket too.
