"I'm sorry..I'm sorry.." Was it right to go after the kid for the attempt he would eventually make? To kill him for the mistake that would doom countless others. You weren't alone when you went back to stop the hellhole the boy would set in motion. You knew one day he would run into the middle of a fight, making things worse causing countless people to die. The backlash not just against the heroes but everyone. You told him what would happen, but it wasn't enough. To kill Atticus was the priority for the other one.

Atticus didn't fight back, he agreed for the chance of preventing so much loss.
