I don't know, it seems like denial and rationalization. A dictator got his family killed(possibly tortured before killing them), there is nothing he can do about it, so he is trying to find solace by believing he doesn't want Kim Jong Il hurt; and to justify why he thinks so, he is imagining good and innocence, when none exists.
He is well aware of things Kim Jong Il did to his family and common masses, and yet he is trying to imagine good in him - I can't find a rational explanation for his line of reasoning.
