D&D is first and foremost a co-operative game and the enjoyment and comfort of fellow players takes precedence over whatever beautiful arc you have in your mind. If you want complete control of the narrative, write a novel.

True for both players and DMs.
Corollary point: as a player, it’s your job to be an interesting protagonist in a way that still allows for the GM and other players to also have their fun. As a player if you’re just there to fuck around, not contribute to the story, or act like you’re the main character, go play a videogame instead.
