This honestly sounds like an amazing quest giver.

Evil Quest Giver: Yes, go and fight the dragon in this remote mountain and get treasure! I hope you survive, hehehe…
Party: (One week later) Wow, that dragon was kidnapping the locals and planning a conquest of the valley! Good thing we put a stop to that, huh?
EQG: Uh… Holy heck… W- Well, you’re just the people to deliver this letter to this outpost in the middle of nowhere! Go now, take your time with the trip!
Party: (One week later) Turns out the guy you sent that letter to was researching occult rituals and accidentally unearthed a swarm of demons. We saved him and found this sword of sacred might.
EQG: Okay, plan C. Join me, and we shall overthrow the crown!
Party: The one terrorising the common folk? We were hoping there was a resistance group we could join!
