2) in any possible scenario I will have a chance to punish the scammer.
But only by punishing yourself.
This is how extortion works.
In this case your punishment is twice as bad as the scammers. If you want to reduce the punishment that you feel, you can only do it by giving in to the scammer and allowing him to win. If the scammer gets punished for doing wrong, then the honest person gets punished twice as much.
