"Oh, you were convicted of a crime, you're a criminal, I can't hire you."

Blind ostracism doesn't help anyone. The prison system and the psychiatric system are two of the biggest threats to a free society. Magical authority to lock you up against your will because they say so. Smoke some pot and end up in jail... say things others don't like and get pumped full of drugs... society is a falser representation of what is could be, masked in falsity, evil hiding under the image of good while the populace is blind to what is happening.

A cage or drugs doesn't rehabilitate people. Psychological work, self-knowledge, is required to change people. Some people might not want to, but this is a community change that needs to be created where there are no prisons, and we all deal with the failure and teach the knowledge of ourselves to elevate everyone.
