What the guy did was inhumane. Dogs fighting it out, nothing fun there imo, its about survival.
Is Vick rehabilitated, that's the real question. Is he genuinelly sorry for what he did to cause so much suffering to man's best friend?
You could say he was sowing his oats, high on the hog, in the prime of his youth, but he made some really bad decisions, unforgiveable to many pet lovers out there.
I say if he's a different man and rehabilitated, he gets another chance.
Some of the best game wardens were some of the worst outlaws on the planet. They changed things around, I believe Vick could too, but its not my place to judge him.
