No I would not. You are correct that an author would not kill their own character in a lame way. But I think the death should be fitting to the character. In my opinion, Revan should have been killed by the Emperor. Drew missed his chance for his character to be killed by the most powerful being in the galaxy. It would have been a good death. Revan's fought countless enemies and defeated them. Shouldn't his death come from a battle that he can't win? I think so.
True, true, eh will see what happens. Perhaps will get to kill him again(if he does come back), or its just referenced that Revan went after the Emperor(again..) and died.
