He tortured and castrated Theon Greyjoy until he convinced him he was the cowering Reek who couldn't remember his own name. His own wife was willing to jump off the roof to get away from him.

Tyrion: Let me give you some advice bastard. Never forget what you are. The rest of the world will not. Wear it like armor, and it can never be used to hurt you. Jon: What the hell do you know about being a bastard? Tyrion: All dwarfs are bastards in their father's eyes.
Thoros: You still mad at us, boy? Gendry: You sold me to a witch. Thoros: A priestess. I'll admit, it is a subtle distinction. Beric: We're fighting a great war. Wars cost money. Gendry: I wanted to be one of you. I wanted to join the brotherhood, but you sold me off... like a slave. Do you know what she did to me? She strapped me down in the bed. She stripped me naked. The Hound: Sounds alright so far. Gendry: And put leeches on me. The Hound: Was she naked, too? Thoros: She needed your blood. Gendry: Yes, thank you. I know that. The Hound: Could have been worse. Gendry: She wanted to kill me. They would have killed me if it wasn't for Davos. The Hound: But they didn't, did they? So what are you whinging about? Gendry: I'm not whinging. The Hound: Your lips are moving and you're complaining about something. That's whinging. This one's been killed six times. You don't hear him whinging about it.
