Considering that Suzaku comes damn close to being one in canon, I'd say this isn't too far off. This is the guy who thought it was okay to have his supposed best friend MIND RAPED in canon so he could pursue his own desires at the cost of justice (as Lelouch and much of Japan, if not the world saw it), and was more than willing to murder Lelouch if he ever broke free of the prison they'd forced him into within his own mind, out of his own selfish desire for revenge due to Lelouch actually taking responsibility (albeit in a tragic way) for what happened with Euphy....yeah. He fits this role frighteningly well. He was NOT altogether right in the head from Euphy's death onwards. Not that he was all that sane to begin, with given his Death Seeker mentality and all before that but....
