I don’t care about his stupid backstory. I don’t feel sorry for him. He is an ass. Even if the guide agreed to die, they abused a mentally unwell person. They consent the esper to suffering by forcing him to be bonded to white hairs. And he went after OP - tried to kill him - to steal his esper. He wanted to do that as soon as he saw there was a esper stronger than the one he already had. That bastard isn’t a good person no matter how he spins it.
