Lex Talionis

I think that the justice system should, as best as possible, try and distinguish between what is out of someone's control, like an addiction, and try to reform them, but if someone is intentionally trying to hurt someone, or break the law, then they should be punished as they have done to others. However, seeing as people are liars, they should be punished with what they deserve, unless it is clearly seen that someone needs help. Polygraphs help.
