I've known people who would encourage rule breaking and then totally rat someone out the instant an authority figure showed up (primarily in school).
Yeah, I thought about mentioning that. But that type of person is a real person with a personality.
The thing I mentioned is just the preset personality choosing the response that they prioritize, which in this situation, produces opposing results. It does not come across as a real person who ratted the thief out for amusement.
