Lmao hell no Nami's declaration was garbage.
Nami was bashing on Ulti for hitting a little kid.
This fucking little kid who was turning Ulti's allies into her enemies.
Whose dog bit half her body like a chew toy.
Who was putting in work for the raid and doing things that would deem her more worthy of being killed than Nami herself.
Nami's morals are trash. Tama is not innocent and did it with intent to hurt the enemy, she deserved to get her ass slapped by Ulti
Tama is an awful plot device but from straw hats point of view she's an oppressed kid whose entire life was made hell by Beast Pirates and Orochi and fought back to gain what they stole back from her, her freedom ;
They destroyed her village
When Luffy met her, they were about to sell her into sex slavery (red light District)
They starved her, she could only eat rice twice year, eating millet the rest of the time.
They kidnapped and tortured her with pliers to use her power (kinda ironic they're now getting beaten by that very power)
See, I wish she stayed in Wano. For a kid she contributed way too much and I'm annoyed as much as anyone by it. And it's normal Beast Pirates Ulti attacked her. But I find the moral talk kind of harsh as it was some kind of morally grey war where every side is equally good/bad when this is a story of a kid standing up to her life long oppressors using the weapons she has. If Tama is not "innocent", beast pirates are 100% guilty. This is clearly not Oda's intent to portray Tama as the bad guy here.
Heck, Luffy crushed a fodder skull with G3 hardening just for wasting a soup because of Tama, despite that fodder never having interacted with her. Zoro even wanted to cut them.
It woud have been really OOC for Nami to have no strong reaction seeing tama get maimed by claws (cause that wasnt a simple slap, it knocked tama unconscious and is likely to leave a scar) because "she asked for/deserved it", nah that's not how people behave. That's not even about morals, you hurt something they feel protective of ( a kid in her case) in front of them, they will have a strong reaction.
I'm not saying Nami morals can't be criticized nor that Ulti is evil for knocking an enemy out as you're free to dislike this scene ofc, that's not my point.
But we off topic so i'm stopping here about this matter.
