While Kimbley was alive it was like, "wow, what an asshole, calm the hell down." He didn't have any inkling that Kimbley might have a role at that time, and was kinda pissed to find out he did! How dare someone who ought to be useful to me go and get himself killed for no reason whatsoever.

After he died, Keyes was the asshole who needed to calm the hell down, and Kimbley became the guy he could say whatever he wanted to and not have to deal with awkwardness or misplaced sympathy or anything else but just an echo chamber of assholery. ...Assholism? Assholics? You know what I mean.

So I guess what I'm saying here is, he thinks Kimbley is an asshole.
