If you pay a player $10k if they win a game, that is the dictionary definition of performance based pay. I believe that is what the poster is replying to.
People have always been able to murder if they want. There can be potential consequences if they are caught and/ or convicted. Similarly there can be potential consequences for leaving your team in a tough spot like this guy did. As someone mentioned, a potential consequence could be he isn't recruited as much after he left the former team in a tough spot. There could be other potential consequences as well.
