The bad guy, Haman, was literally one of like a hundred or so survivors of a people the Jews had genocided. He was the grandson of their last king, in fact. Manages to get himself a good job working as an advisor for the king of the Persians, just trying to help the last survivors. Tells the king "hey, these hebrews are fucking genocidal fucks who killed my entire people. maybe you don't want them around in your kingdom."
king says, "you know what, you have a point. I'll take care of it as soon as I handle my current wife situation. Bitches be crazy, yo."
Then the Jews manage to get a hot little Jewess in the kings bed as the new queen, and she literally bangs the king into believing "haman lies, that genocide never happened. Where are even the body's? he's just jealous because he can't get pussy like you can."
At which point the king goes. "You know what? dat ass tight, fuck him."
So they kill Haman. And cheer the genocide of his people and his execution every year with parties and fancy cookies.
