Angel, Season 5

[Agent Hauser aims his shotgun at Angel]

Angel:
You know that won't kill me.

Hauser:
It'll hurt. That part's fun.

Angel:
Agent Hauser, I'm honestly beginning to suspect that you're not part of the solution.

Hauser:
You really think you can solve the problem? Come into Wolfram and Hart and make everything right? Turn night into glorious day? You pathetic little fairy.

Angel:
I'm not little.

Hauser:
That's exactly what you are. You're minuscule. A dust mote on the shelf of that great institution. Now, you think I'm just a trigger-happy jerk who follows orders, but I am something you will never be. I'm pure. I believe in evil. You and your friends, you're conflicted. You're confused. We're not. That is why you are gonna lose, because we possess the most powerful thing in the world... conviction.

Angel:
There is one thing more powerful than conviction. Just one. Mercy.

[Angel kicks Hauser's gun up, causing him to pull the trigger and blow his own head off]

Wolfram and Hart agent:
(Shocked) What happened to mercy?

Angel:
You just saw the last of it.
