The X-Files, Season 8

Krycek:
I could've killed you so many times, Mulder. You've got to know that. I'm the one that kept you alive. Praying you'd win somehow.

Mulder:
Then there really is no God.

Krycek:
You think I'm bad. That I'm a killer. We wanted the same thing, brother. That's what you don't understand.

Mulder:
I wanted to stop them. All you wanted was to save your own ass.

Krycek:
No. I tried to stop them. Tried to kill Scully's baby to stop them. It's too late. The tragedy's that you - you wouldn't let it go. That's why I have to do this. 'Cause you know how deep it goes. Right into the FBI.

Mulder:
You want to kill me, Alex, kill me. Like you killed my father. Just don't insult me trying to make me understand.
