[ Shinji grits his teeth at that answer. No, he doesn't understand. (Altruistic reasons like those are not why he piloted his Eva, after all...) Nor does he care to, right now. He just knows/hears that Kaworu would be one of those people out there. And he wants to protect you. (Especially after... being convinced he wasn't going to see you again; that he's not supposed to see you again, yet here you are.)

Looks like there's no convincing Kaworu, is there? Shinji, stop trying. Just stop.]

But. You said fighting isn't all you have to do to help! If they protected you, it means they want you alive.

Please. If you're that worried, then let me pilot that [once more.], for you.
