How about a Stain!Jaune AU? Where he kills other huntsman because his beliefs makes him believe they didn’t become huntsman to help people?
That's what they called the destruction of Everwoods. A mistake. Poor judgment. Lack of hindsight. Bad call of the huntsmen group...
Those bastards went after the big bad Grimm they couldn't handle. Those same bastards then ran to the town and attracted the monster to them.
And when his father blocked their way and told them to fight the Grimm they brought here?
They tore their way through him and others.
Huntsmen were heroes... So why did those heroes run the moment the battle wasn't so easy? If they were the brave warriors books painted them as, why were they crying and begging for their lives so desperately now that he had them at his mercy?
Didn't matter. Wouldn't bring those dead back.
Sti, it certainly beats moping around.
He tells himself that these guys are all. That now he can set back into simple peaceful life.
Too many fakes walking around free and unpunished. Too many people putting trust into the frauds and liars. He will show them the truth. Yes, he will...
Even if he has to stain his hands red and his heart black.
