[It's what she means. Not once has Nami ever thought she did the wrong thing by taking up Arlong's deal-- it was the only thing open to her at the time and she took it. Telling your mother how you spent the next eight years? How painful it was? Despite Bellemere's words, she doesn't quite want to tell her about that.

But she deserves an explanation.]

...

Arlong offered me a deal to buy back the village from him for 100 million beri. And in return, I'd join his crew and draw maps for him.

So I decided I'd steal the money from pirates. That's how I met Luffy. Only when I tried to steal from him, he followed me right back to Cocoyashi.

[Shortest version she's ever told, but. Her hand goes up to her shoulder.] I took the tattoo off the day before I left again with Luffy's crew. This one is just all my love of home. It's a free and happy place now, Bellemere-san. It just took a while. Everyone else is okay.

[Nobody else died.

Just you.]
