Andrei felt he was right, killing those people, he felt guilty, but he still convinced himself that it was a good action. You wanted him to change, but he couldn't, not for more than 2 months atleast. Andrei tend to be unable to feel empathy and remorse. He can suffer emotional pain, and may feel loneliness and social isolation. He may target his aggression towards himself as well as others. He is manipulative that he didnt even realize he did.
