Weird translation in One Piece Episode 132?
I wouldn't say the translation is off.
Nami is trying to convey that simply saying 'sorry' is not going to resolve the issue at hand.
Similar to how saying sorry to the marines would not make the crew any less of a wanted criminal.
Hence I don't care if you are sorry! doesn't really covers what she tries to convey. She may still care about him being sorry, but in the end it's only a cold comfort. It will not fix or rectify the situation.
Or in the context of the episode, just saying sorry is not magically going to repair or fix the damages done to the map. Which she just put a lot of effort into making.
So something along the lines of Being sorry is not going to fix this map! would probably better reflect what Nami was trying to say.
