Look, you go out there, and you're going to fight a player. You win, you lose, maybe he's better, maybe he's not. But in the end, what's really the reason to justify the "bad sportmanship crappery" that happened in the event? Like why would someone do that in the first place?
Edit: Because after something like that happens, it also makes the other side react. And it creates a trend that leads to what we witnessed.
