Alexander Foster (Lost Days)

Alexander Foster a man in his early thirties, who works for the CIA as an "enhanced interrogator", which according to him later is an euphemism for "torturer". He suffers under heavy delusions, that his acts of torture and manipulation will make the world better one day. He often tries to justify his actions by saying that "I hurt those that deserve this". 
He suffers a total breakdown, when Alan Langley, the true mastermind behind the Zaavan case, reveals humans rotten nature to him, which forces Alexander to acknowledge that he is indeed a deeply troubled person, having lost his mind for his as he called it "crusade against terrorism", and that he can't let go of his families death at the hand of terrorists.
