Daredevil and Castle in “Unfinished Business”

Daredevil

I can't let you start a war for the wrong reasons.

Castle

Maybe a war is what I need. Maybe I need that. These people, they took my children from me! They killed my kids! Don't you get that?!

Daredevil

We do right by them! Help me. Work with me to find the men who gave the order!

Castle

And then what, Red? We gonna-- We gonna bring 'em in for justice, is that what we're gonna do? Your way's bullshit, Red, it doesn't work! I need 'em... I need 'em gone, it's gotta be permanent, it's gotta be finished!

Daredevil

I-- I understand. You're right; my way isn't working. So maybe just this once... Maybe... Y'know... Your way's what it's gonna take.

Castle

Wait, "just this once". No, no, no, Red, that's... that's not how it works. It's just... You cross over on my side of the line, you don't get to come back from that. Not ever.
