Krycek and Mulder in “Existence”

Krycek

(pointing a gun at Mulder) Doesn't seem fair now.. Doesn't seem right. Coming down to this.

Mulder

What do you know about fair or right, Krycek? You're a coward.

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.
