It certainly doesn't help his case. If you have had troubles with the law prior to a new crime, it gets taken into consideration negatively by the judge. Same with cheaters. It means he is a cheater by definition and has the moral compass to cheat again.
This isn't a court, and it isn't criminal behavior. If it was a court and it was criminal behavior, we'd expect innocent until proven guilty and the benefit of the doubt. Which no one is giving Hans.
