Dutch van der Linde from Red Dead Redemption
To the protagonist of Red Dead Redemption, Dutch van der Linde was like a father. He took Marston into his gang as a young boy and taught him to read and write and be the man he was when the game picked up. Dutch is one of my favorites not because of his sinister villainousness, but because he wasn't even a villain at all. He rode in a gang and robbed and killed many people, but to John Marston hunting down and killing him was like having to kill his own father.
