For myself, I think Vick might now realize that it's LEGALLY wrong to murder and torture dogs, but he will most likely never think it's MORALLY wrong to do so. He argued he was innocent, until he realized they had enough proof against him.
I don't think he should still be punished per se.. but I would want to think that the NFL and teams would not want such a scumbag as a star in their organization. There will probably be a team that takes him on, and in a few years no one will remember his atrocious actions.
That's the truely sad part. Other than a few dead dogs, and a few people who had to deal with the aftermath first-hand.. no one will think about it after a while.
Still means he's a scumbag.
