Punishment should be enough to deter and equal across the board... A player who acts out agressively repetitvely should just be banned outright. Likewise, a rapist who re-offends should have his knobb chopped.
Yeah I don't disagree with that.
However biting in football has gone a new level with whats happened with Suarez.
I remember when Defoe bit Mascherano when he was at West Ham at it got laughed off almost, he got a yellow card in the game and the FA didn't take it any further.
