That part he's not sure he can agree with, actually. On Kai's end, one of them just had the unfortunate event of not dying when he should have, and the other was just trying to get him somewhere safe. Shinji's actions, be they coincidental or actively malicious, resulted in an immeasurable amount of collateral damage - if anyone here's done anything objectively worth punishing, it's Shinji.

But, he keeps that knee-jerk reaction of protest to himself. He's not sure he can believe it, but he doesn't want to push that sentiment away either.

"I... don't want to be that person any more," he manages to eke out after a few moments of still silence. Just because he can't agree means it's anything he ever wanted. "You've helped, a lot."
