I have been watching Smallville and the one of the things I was thinking about was what happens when Lex goes bad. And while it will happen. I don't think he would hate Clark. If Lex really hated Clark. With one phone call he could destroy the Kents (ie-call in a loan, etc). I think a better way would be him becoming more distant and cold. He doesn't hate Clark. He just doesn't care about him.
