I don't think I'll ever not side with Graham. I have been waiting to long to meet the Burned Man, I am not going to blow him off when I finally do meet him. And I hope they make him essential, I don't think it would make sense for the Courier to kill him, especially when people say that Graham is pretty much immortal. He was set on fire and thrown into the Grand Canyon, I don't think theres anything the Courier can do to hurt him.
are you sure? he may be a super tough badass, but hes still just a mortal. a hollow point AMR shot or 2 from a foot away to his severed head should do the trick dont you think?
if we can kill him it should be kinda like the ghost people, gotta cut his head off.
anyway i have 3 characters, and another that i will make......soon.....after all dlcs are released, so im sure ill help him out at least once.
