It'll be hard to say for sure if I'd be able to do such to my club. I don't think it's something one could imagine when he's not putting on the shoes of the man in the story. Ordinarily without being hysteric I'd do that if my club guarantees to lose the game. I mean who would know he'd lose a game against a worthy opponent and still not bet against his club. Working with the club is quite very different from being a fan. Lots of fans can do it, but employees trust their club and wouldn't think of losing any game. It's more like going into a competition and purposely lose because you staked against yourself. It sounds weird to be sincere.
It is against the ethics of most clubs for players or employees bet against their clubs or employers. This is because they can manipulate these games to favor themselves. Many players have been sanctioned by clubs and sports bodies because they engaged in match-fixing or betting against their clubs.
Your write-up only defines how deep gambling have impacted negatively to the genuineness of most games like football. Hearing multiple cases of footballers who engage into fixed games derails the fun of football. Indeed it's meant to be a sanctionable rule. They actually make huge amount of money sabotaging their team. It should be a felony. Affecting an entire team and endangering their league success is quite unbearable coming from a well paid employee. A single player can easily impact the game and cause losses to his team. Have been wondering how this employee who doesn't play in the pitch could attribute to his team losing a game.
Let's say they won under the same conditions then I'd be happy with their win even though my bet lost.
