To me, it seems like while they could very well have had this opinion of him before he killed his parents, after he did it he would have to be dropped. The KGB has proved able to make bad decisions, but that would just go beyond the pale for me. There's no second chance after you flip out and kill valuable agents in an adolescent rage because you can't see your girlfriend. Jared did more damage to the Illegals program than Larrick and Stan combined and he doesn't even really regret it because he's still clinging to the idea that he's the real agent here.
