Actually i don't agree with vengeance. It is for the Police and the State to impose the sanctions and penalties the people's representatives have enacted.
That's why i don't believe in the death penalty. Despite it, people still commit capital offenses and all it ends up being is the taking of a life when no other is in danger.
I'm an atheist personally, so Biblical or any form of religious philosophy has to be to in agreement with my own personal sense of morality. I agree with not killing, stealing, baring false witness, but I cannot agree with an eye for an eye and a tooth for a tooth.
Revenge isn't justice, and I'd prefer to live in a society where the Law is not based on retribution but on imprisonment. Revenge if often bloody, over the top and uncontrollable, hardly the example a society should live by.
