Smokey, you hit the nail on the head...that this was done to punish George and keep the others in line. A 'either put up or shut up or you're out of here'. I think if George does come back he writers won't want to write for him anymore, he'll be an afterthought and probably just process evidence in the lab. If he doesn't come back and they let him out of his contract, I'm afraid it won't even been mentioned. He DESERVERS and WE DESERVE a probably good-bye for Nick and DO NOT kill him off.
