I'd say landing on a rocky ledge, suffering the horrendous pain of dislocated shoulder and shivering through the night (probably by this time afraid, cold and in great pain), then being made to feel like a complete idiot afterwards, is punishment enough for what was a stupid act by a young man. \Bet he doesn't do anything like that again
We all do daft shit when we're young. Some of us get away unscathed, some of us do not.
