@Raydnt What he said and what he'll do aren't necessarily the same. He is
broken. Whenever he gets some time to himself, when he lets his mental guard down, memories of his wife
always pop up. He burns for revenge, he spent years thinking of nothing else. It's his
raison d'etre. As he is now, I don't think he'll have the will to go on after Two-Faced is truly dead.
Of course, I hope and expect he'll grow and find reasons to keep going. Seeing Kudlak and the vampire corruption will likely be a catalyst. I'm guessing Kudlak will turn completely evil, and Keigo will purge pretty much all vampires but Momo. Also, I don't believe Two-Faced really went rogue. I think Kudlak set him on this path, for whatever reason.
