I started a mini campaign this way. Two of the characters were chaos gremlins, and the third was their lawyer babysitting them for their community service of defeating the local monster.

Dungeon Master Waller is forming a kind of… Suicide Squad.

Player: "Oh well, here I go killing agai-" DM: "Mark of Justice" Player:

I'm imagining a scenario where the local power has a dungeon awakening near town, and they've heard of other Mayors who sent a crew down with a rogue on parole, but is more of a 'if one pregnant woman births the child in 9 months, two pregnant women can do it in 4.5 months' type thinker, so he packs anyone with a bit of a criminal record into wagons, dumps them all into the dungeon and throws in a bag of knives and tells them they can leave when they defeat the great evil. The PCs are the party who he meets and sends in later because this necromancer problem just hasn't gone away like he hoped.

Warlock, tapping on cage lock: Wakey wakey Paladin: Come at last for your blood sacrifice, heathen? Warlock: Disonia is a vegan god of chaos, not that I expect zealots to understand doctrinal nuance. No, I'm here to talk, you goodies like to talk right? Paladin: .... perhaps.... Warlock: Can we agree that sometimes there are lesser and greater evils? We're putting together an expedition into the Dark Lands. A crusade, if you prefer...

Considering the month, I read the first line of this very differently.

Ooooooh you dirty, hahaha

You have no idea.
