Everyone is responsible for his own actions, and whatever he does, he has to bear the corresponding consequences. If you have made mistakes before, it means that you have not been able to control your emotions or behaviors well before. When such people work as police, civil servants or lawyers, they may no longer be able to control their emotions or behaviors well, which may easily lead to serious consequences.
It's not that you don't trust, but that your behavior makes others unable to trust.
