I don't particularly care if Kris doesn't want to be my friend. I've met many people who I simply cannot befriend. All I care about is that Kris does not die, and I do not die, and we do not eliminate eachother.
If Kris does not want global annihilation, and their alliance with the Knight is for some other, non-evil purpose, then I will aid them in whatever they seek and leave it at that. I do not expect them to befriend me after I do this, either. I'll just do it because I've been tasked with seeing the experiment through to completion, and by god I'll bring completion to all who witness my SOUL.
