Good analysis DT. But, of course, that analysis eschews Michael turning to evil which was the original question in this thread. As I posted above, I don't think evil exists; there's only what we do. If you want to label Mike's actions as evil, fine. But, as your analysis points out, it wasn't evil that caused Mike to do what he did; he was exigent circumstances. So, there was no turning to or becoming evil by Michael.
