I saw this one YouTuber who does one piece agenda videos, reads the latest chapters, etc etc and he was flat out MAD since Oda keeps saving characters that we thought were going to die. Personally, I'm with him on that. Don't get me wrong, Kuma is a GOATED character and so is Vegapunk. I can see Vegapunk getting saved since his brain was still in great shape, but what was the whole scene with him and Sanji for if Vegapunk knew he could be brought back? And Kuma is no exception. As bad as this might sound, Kuma should stay dead. It takes away the sacrifices he made for Bonney and the hard effort other characters went through to save Bonney and Vegapunk.
That's essentially Oda bringing back Ace out of nowhere. Like what was everything for? The Koby speech would've been for ABSOLUTELY NOTING since both sides lost a lot of people for fighting for what they wanted (marines wanted Ace executed since not only them, but a lot of innocent civilians in the world saw him as a dangerous criminal while the Whitebeard pirates saw him as a loved friend and a valued family member while Luffy ofc saw him as his beloved brother).
All those sacrifices would've been in vain. Everything Luffy did in the war would've been for noting since Ace's death is what eventually motivated him to become stronger to protect his friends. His death was his reality check that their are people far stronger than him that he couldn't beat during the time. Sabo wouldn't have gained his memories after realizing Ace's death as well. A lot of stuff everyone in that war fought for would've been for nothing. I honestly had enough of Oda bating us to feel for a character cause we feel like this character is going to die just to bring them back like bruh, what was the point of me crying if you're just going to bring that character back?
