Well, maybe, but that's half the fun, ain't it? If they didn't want us to think too much about it, they wouldn't have given us too much to think about, now would they?
Anyway, yeah. I think whether the Big E had it coming or not depends on your point of view. From a human point of view, yes, some of the crap he pulled is inexcusable, as is a lot of the crap he was going to pull, but from a cold and calculating Old One's point of view (i.e. His), then no, he had avery good reason for evrything he did and the ends justify the means. It's just ironic that those means ended up stopping the ends and becoming an ends unto themselves.
