'At all costs' means something must be achieved or avoided, no matter what the consequences or sacrifices. It's like saying 'no matter what' or 'by any means necessary.' Imagine a hero in a movie vowing to protect their friends 'at all costs.' Or a student determined to pass a class 'at all costs.' It emphasizes the extreme importance of the goal. It signifies a high level of dedication and determination, sometimes bordering on recklessness.
