Both good!Lex and bad!Lex are ridiculously grandiose. Bad!Lex wants to conquer the world, good!Lex wants to change the world by abolishing hunger. It's interesting that even when you split out the good and the bad, both Lex's want to remake the world in their image. That is a fundamental part of what makes Lex who he is.
To quote Lex in the lab, "we've succesfully destroyed the genes that make a plant weak, giving it the ability to thrive under the harshest conditions, but the process also effects the fruit it bears, and not for the better." This recasts the dichotomy of Lex: it's not about the 'good' one and the 'bad,' it's the weak and the strong. If you look at the statement even more metaphorically, it sounds exactly what Lionel Luthor has always tried to do with Lex. Destroy what makes him weak so that he can thrive in harsh conditions (like, say, the Luthor family). But it effects the fruit it bears, making it rotten. This line is so heavy-handed I'm amazed I didn't catch it the first time. On the second run through it sticks out.
I'm also enjoying just how playful bad!Lex is in his endeavours. Even when confronting Clark about his secret. When this has played out before, Lex has been hurt. There is only one moment when it looks like bad!Lex is hurt by the revelation. He skips straight into the Naman-Segeet (I cannot remember how to spell that) mythology.
