Then what would be the point?
Why did they kill him? I could count on two hands the number of scenes he appeared in, and on one the number of his scenes that were meaningful or even memorable. He was barely a character. If his death is not meant to serve some ultimate purpose that will be revealed later, the only explanation is that the actor had to leave the show. Something that permanent, with that much emotional weight, for someone we have barely seen, had to be done intentionally and isn't something that would be so quickly reversed like that.
