Well that's the thing because they have no remorse or fear of consequences psychopaths think they can do whatever they want, so if i was a psychopath I wouldn't look for a reason to justify my actions i will simply do as i please, what i think the author is doing is making him more empathetic so he could be accepted more by the audience as the lover of the main character.
Srsly why would he help that girl and kirin? I thought he was a psychopath, psychopaths are merciless and lack the ability to empathize with anyone
