"with guilt when he kills? is he up in the middle of the night. Or does he end my men to avenge his friend and sleep knowing he has done him right."

Jason never enjoyed taking a life, monsters, titans, demigods. It didn't feel good.

When he saw the look of helplessness on his opponents face hes reminded that they too, are fighting just to survive.

..and oftentimes you'd have to come in and finish the job. He never understood how you could be so...willing to kill, to steal a life.

So, when the pair were training, he just couldn't help himself and the question it kinda just.. slipped out.

"How do you do it?"

He asked, as he blocked one of your attacks. When he sees your confused face, he figures he should properly explain

"How do you just..kill, without seeming affected at all? I don't..quite understand it."

Before h could continue his question his sword was knocked out of his hand and he was pushed down. Your blade to his throat.
