I hope Vick has changed. Honestly. I accept that he has done his time. BUT.......
I would like to say that prison is not really a place for changing though. More often than not, it is a place to learn how to become a better criminal and a lot of people return after their release. Prison is supposed to be a place for "rehabilitation", unfortunately it's not.
Entered prison:
1998 561,020
1977 147,895
Conditionally released who return (I didn't see the facts for those who served all of their time, but I assume conditionally includes probation, etc.):
In 1998 209,782
In 1977 it was 19,617

I think that is almost 40% back in 1998 and from the pattern in the stats, that % goes up every year.
Either way, only time will tell. Best of luck to him. Maybe now some kids will grow up KNOWING that dog fights are wrong—even if they were raised with it.
