I was quickly going through moments in YuGiOh recently and was reminded of YuGiOh season 4, a filler season. In this season, there is a card that allows you to gain a bunch of good effects in the card game, but makes it so the loser of the game loses their soul. In a stakes-less duel, The Pharaoh is given this card by one of the bad guys because he's convinced The Pharaoh is evil and will use this card to win a children's card game.
... So The Pharaoh does do that and causes Yugi's soul to be lost after he loses the duel.
And to be clear, before the evil card was played, there were no stakes whatsoever to the duel.
The show tries to justify this by saying that "the card influenced his mind" but like... The Pharaoh had been pretty heroic for the last over a hundred episodes and now he's attempting to kill a dude while gambling Yugi's soul.
It's just a massive escalation and feels like something that could never happen outside of filler.
