Betraying the trust of others in any context is wrong, and has moral implications beyond the immediate harm to the counter-party. Your GoT example is nonsensical: it ignores the difference between fictional immorality and real-world immorality. Your assertion that this article is mere spectacle is baseless. It seems to me that you give no weight at all to betrayal, and I believe that has real implications for those considering taking you on as a counter-party in any context. Heck, I'd probably avoid playing board games with someone who espoused these kinds of views; apart from cheaters being less fun to play with, I find the "If you get away with it, it's fine" attitude to trigger a strong feeling of disgust, akin to the stench of fresh shit.
