Pete has admitted to gambling on baseball, and even the Reds, but he never bet on the Reds to lose.
Pete never gambled with his life - using steroids and drugs - in order to set an illegitimate record. He gambled on his own team to win. He had a gambling addiction. Lots of people do.
Holding a grudge for the sake of holding a grudge is unhealthy. His record as a player stands and he’s been used as a bad example long enough. Murderers get out of prison in less time than Pete has been disgraced.
