Most people don't treat their line setting as holy scripture. Besides, nobody stops you from putting your actions on a sliding scale.

Did your good friend not repay his loan? Okay, what's the size of the loan, and how did they react when you reminded them? What's the circumstances surrounding the loan itself - did they borrow for the down payment of a mansion, or did they borrow to buy cheese?

Also, if you're treating your life as a game theory set piece then perhaps that's a place where you should start making changes. Just sayin'.
