Yep, Nami became a money hungry person due to trauma.
Doesn't bother me except when she beats the guys up over it, but, I get it; it's because Nami knows that sometimes, money talks, and people only listen to money. Nami craves money so she can spend it for the people she loves.
Camie's auction is a great example of this, look at the raw horror on Nami's face when she realizes all their money isn't enough to save Camie's life from the Celestial Dragons:
It's the same terror as when Bellemere died.
Nami is an inherently problematic character, and I have no problem with people calling me that out, she is a pirate/thief who has done plenty of bad things in her life.
But, I hate how One Piece fans treat Robin like some precious little angel when she was willing to destroy an entire country to get the Rio Poneglyph, and then act like Nami is some new evil or something. Robin fans hate this one panel.
And I AM SUCH A MASSIVE ROBIN SIMP, but, fuck, yeah, she's done bad things. Robin has done horrible things, Kuzan was right to test her.
That's the whole point of the series, that good and evil are just stupid words used by stupid people, and life is way more complicated than that. People who do cruel things can change and become kind. Robin used to be a horrible person, now I think she's one of the kindest characters in the series.
EOS Socialist Nami?!?!?
