So you can avoid being punished by not predicting potential punishers well enough, or by deciding to do something regardless of punishments you're about to receive? I'm not sure that's good.
Can you say more about why you don't think it's good? I can think of several different reasons, some more valid than others, and the context up to this point doesn't quite constrain them.
Here's an edited version of a puzzle from the book "Chuck Klosterman four" by Chuck Klosterman.
When should you punish someone for a crime they will commit in the future? Discuss.
