Norman might also be a murderous psychopath, but I get his act here. He's being the "stern father." Sure, he also loves throwing civilians off of very tall objects, but he can't give Bullseye that relateable "in," or it invalidates his attempt at discipline.
I hope Dark Reign gives us a little more look to Norman like they suggest, that it really isn't Norman who's the cackling chaotic sociopath, it's his split personality. On the other hand, Norman is a scheming evil sociopath, and has been all along.
