That's not the point of the justice system. Justice is not about retribution, justice within criminal contexts is about punishments within the realm of what is good. Punishing someone for past behavior that serves not future purpose is retribution. The justice system needs to be changed if it's about tick for tack.

For example, we don't need to give somebody a life-long sentence for a crime that they're obviously and apparently not going to repeat again. We have to take into consideration relative changes.

An obvious example here is the ongoing case with Danny Masterson, a crime that was committed 20 years. He's now a family man and a father. It makes no sense to give him 30 year in prison. That is just cruel. Our justice system has failed, not only him, but also his family - like his daughter, who will now grow up without a father. What good does that do???

We have to become forgiving and tolerant as a society, things are becoming desperate.
