The only thing "we know" about his history is he was some genetically altered freak who try to take over the world, failed, was put on ice, and sent off into space. What does that have anything to do with potential story lines besides being a starting point?The fact is, we know Khan's history. I don't care whether the character's do or not. The movie is supposed to entertain us and if we know the character well, and a lot of us do, we are not going to be surprised nor applaud when his eventual demise happens....
Khan has a son? Maybe in fanon, but not in canon.
And who's to say that history can't be altered a little as a means to an end, a few crybaby "fans" having a temper tantrum on a web forum?
And if your only fear of a antagonist is his inevitable demise, why even bother having one at all?
