A criminal came to his private property and attempted to steal. He was able to keep the person there - for less than ten minutes - until that person was arrested. Presumably that person is in jail now or at least on probation.

Please explain how just letting this person steal leaves the world better than having him get punished for his actions. When victims of crime shrug their shoulders and just say "aw shucks" it incentivizes more crime, which makes the world objectively worse.
