What the hell just happened? Why would a guy defined by his cowardice and sense of superiority commit suicide by nuclear explosion, and die with what he thinks of "common rabble"?
A guy like that would only go so far if he was actually dying or assured of his death, but that isn't the case here, he just got his life spared, so I really really REALLY doubt he would do such a thing.
Well, whatever. Our MC is probably hungry, eating a nuclear weapon or two should satiate him.
