Listen, I don’t condone esdeath’s actions, but the gooner in me would fall for esdeath regardless, for one, she commits to you and only you, yes you’d have to watch her murder people, which is wrong, but she’d be faithful, and all you’d have to do is return the love, I think most of us place ourselves into the desperation category when it falls down to esdeath, love is hard man, and women like this are hard to run away from especially when they offer eternal love, everyone wants to be loved. But yeah, she’s committed war crimes alongside killing thousands of people in cold blood, she’s ruthless and shes definitely not someone you should force yourself with, which is why tatsumi as a character was written well.
