Well, the only reason to kill him is for his armor and pistol. You get nothing else for doing it (no dialog options, no satisfaction with Caesar, no nothing) and since you get his pistol and armor at the end of the DLC, it's really not worth killing him.
Of course, if you're going to do it for your own satisfaction, then by all means go for it. (But it won't really be worth it)
