punishment

I have a question: how long should Michael Vick continue to pay his debt to society? If he was tried, found guilty, sentenced, and did his time, how much more should we require of him? When is time served…time served? And once a man serves his time, should he be allowed to work at his livelihood again? What does restitution and penitence look like if a person is not allowed to re-enter into society? How is change measured for an outcast?
