I would say this easily goes either direction, that someone capable of this level of introspection and empathy would be very good at accomplishing the various evil aims he seems to have been capable of. This is often what people are abbreviating when leveling accusations of psychopathy anyway.

Not sure how the second bit follows - one can be a serious psychopath, sociopath, cartoon villain etc and it wouldn't change that the tone of the memo I is pretty obviously farcical, despite what the contemporary media read it for.
