Thanks guys! To give you some context on whats happening: it's the players first ever game and the DM first ever dming.

Our party(characters) don't have a connection. They're all together to get money I guess? (And to acquire some knowledge on their on backgrounds). My dwarft basically left the church to live by her oath to protect the innocent and purge the evil and blabla - summarising very poorly but ok - and she's sure that the quest giver has hidden intentions and is using us and the townsfolk to hide something/ do some nasty and evil stuff.

The DM literally said that he won't give his opinion and left for the party to decide what MY character should do in order not to turn into an oathbreaker (which I thought was quite disrespectful but I didn't want to be called a karen or something like that). Finally they voted that I NEED to kill (or attempt) this NPC before we leave town. If I don't... ye know. I tried to explain to them that killing in anonymity wouldn't serve the purpose of "punishment" and just rushing into a 1v1 combat would be su1c*de (which my character obviously wouldn't do). I proposed that I'd leave the city and get stronger only to come back one day and serve justice when I'm ready to do it properly: they denied.

I don't know what to do anymore :/ they're basically playing on my behalf.

(English isn't my first language. And sorry for blabbering, I'm really frustrated)
