What would the skull faced man rather do than go to room 101?

From the text:

‘Do anything to me!’ he yelled. ‘You’ve been starving me for weeks. Finish it off and let me die. Shoot me. Hang me. Sentence me to twenty-five years. Is there somebody else you want me to give away? Just say who it is and I’ll tell you anything you want. I don’t care who it is or what you do to them. I’ve got a wife and three children. The biggest of them isn’t six years old. You can take the whole lot of them and cut their throats in front of my eyes, and I’ll stand by and watch it. But not Room 101!’
