No it shouldn't.
It should be the understanding of a society that no human being is just 'bad'. A human being became 'bad' by a definiton of a society due to circumstances like upbringing, environment etc. and a society which failed you.
Prison is the removal of you from society due to impatibility of current values and should help you become 'better'.
Be happy that you had good/avg parents, the mental strength to help yourself, money, luck, body strength, whatever it was which allowed you to comment on HN instead of being in a prison.
