There is so much justification in society as well. We justify sending convicts to prison where they are exploited for profit as slaves, and often times attacked by guards an inmates alike.

We justify this because these criminals deserve to be punished. Few stop to consider how many false convictions there are and how racist the system is. Few stop to consider that this type of revenge only hurts society further, regardless of guilt or innocence.

True justice doesn't care about revenging the past. True justice only cares about making the future better.
