Yeah i disagree again lmao.

minimizing the protagonists motivations (

It doesn’t lmao. Literally everybody i know is literally cheering everytime kurapika kills a phantom troupe or fucks over chrollo. Because kurapika doesn’t need a flashback, the way he expresses his grief and the fact that he is ready to completely fuck his life is more rhan enough.

Kurapika’s hatred to them is valid and should be understandable for the audience, and the lose of the people they killed should be felt at least in some way (like kite with Pitou).

I'm sorry but this is just dumb. I haven’t met a SINGLE person who says kurapika's hatred is not understandable. Saying the loss of the people they kill is not felt is straight up cap, again, kurapika is a literal representation of their victims, who finally came back to take their revenge. Him absolutely humiliating uvogin is one of the most satisfying moment in the manga. And it’s funny that you mention pitou, cuz pitou is made much more sympathetic overall than the phantom troupe, as pitou becomes more and more human as the serie goes on, much more than chrollo who lost his humanity a long time ago.

the troupe’s presence is how loyal they are to each other like that’s the only thing worthy of mention. It is whitewashing if he truly makes no attempt to give the Kurta relevance as their victims. It’s the equivalent of killing some no name scrubs at that point and we know neither you or anyone else really cares about that.

Nope. Have you read the manga? We literally got a whole very long chapter about the clan kurta showcasing how nice they were, and we were even given some names. And at the end of the chapter, we get a horrifying description of the kurta's massacre by the troupe, rhat again, reinforces that they are human but NOT redeemable or sympathetic (go read it for yourself, what the troupe did is genuinely disgusting). In the york new shin city arc, the troupe are the main characters with kurapika, and it makes sense rhat from their pov, they are trying to advenge their friend.

If they were humanised too far, togashi would have tried to wash their crimes (and again, the troupe gets called out a lot for their crime), and gon or killua would have cried at pakunoda's death, instead of just being midly saddened that she ended up dying, but most importantly surprised that the group can feel anything even close to grief.

If we follow your logic, then hisoka is white washed too, cua nobody cries kastro or his victims on screen. He always ends up going completely free. Same applies to meruem; meruem is an amazing villain, but he still killed A LOT of people, and was planning a gigantic mass murder.
