Fitting the theory in the Batman v Superman

While the latest trailer for Batman v Superman did reveal a bit more about Lex Luthor (such as the fact that he does know who Clark Kent really is), the character still remains a mystery. But we can always go back to the previous trailers and see that Jr. sees himself as a savior. The whole line devils come from the sky seems to suggest both that Superman is a peril for the world, just like it seems to suggest that Lex considers himself a fallen angel who came to save the world from other fallen angels.
And this looks like a classic case in which the villain considers himself a hero and justifies all his actions in this belief. Furthermore, if we take a look at all the religious imageries from Man of Steel, having Luthor as a second fallen angel is something Zack Snyder would certainly approve.
Then there is also the fact that Lex knows something about Kryptonite – how can he know that this piece of rock is potentially lethal to a Kryptonian, if he hadn’t tested it in some way? Sure enough, he might have done some experiments on Zod – but we hardly believe that. After all, he knows to keep the kryptonite sealed in a box…
