Lex Luthor's Plot

I think in one of the next movies Lex Luthor will use superman's son for his own personal use and power. Lex does say in Superman Returns " Gods are selfish beings who fly around in little red capes and don't share their power with mankind." Therefore he is jealous of superman's powers. I think that he might use superman's sone to create a evil superman, now that would be cooler that the Superman III fight.
