So we all know the story. Hope allegedly kills millions of people resulting in Bishop growing up with a shitty M tatoo and wanting to kill the bitch. He then tries to off her as an infant fails in the most embarassing of ways and then kills billions in his attempt to kill her. For many, this completely ruined the character and there seemingly is no Hope for redemption. Or is there.
In responding to a post in another thread, It dawned on me that Hope is in fact Bishop's best hope for redemption. Let's assume for the sake of argument that Hope did in fact kill those millions of people. The whole premise the X-men are working of is that because that future hasn't happened Hope has a chance to avoid killing those millions. If she does then Bishop would have been proven wrong and would have killed those 9 billion people in vain.
Yet if Hope can avoid killing millions either by being killed or simply by being good then Bishop never grows up in the concentration camps and hence he never has a reason to try and kill Hope and then never goes into the future and kills 9 billion people. In effect the Bishop that killed 9 billion people ceases to exist because the circumstances (Hope killing millions) that precipitated his going nuts never occurs.
Now the complication here is if you subscribe to the the theory that Bishop did kill those 9 billion people on the basis of the many worlds theory ie every decision you make creates an alternate reality. However, if that is the case then that also means that in one such reality Hope did in fact kill those millions of people. So you either have to accept that Hope and Bishop are murderous bastards or that Hope and Bishop equally can change/avoid what they appear to have done.
Of course, Bishop could just be an idiot and been mistaken in believing Hope killed those millions but that wouldn't be any fun. Isn't time travel neat?
