Oden wank is well-deserved wank though... he basically was the ONLY person to fuck up Kaido and give him that PTSD.... Mind you, Kaido faced Akagami 2 years ago, not sure what happened, but he doesn't have Red Hair PTSD....
The wank from other character is normal cause Oden is a "Samurai Luffy" his character in flashback, his spirit, adventure, all Luffy type.. basically a Samurai Luffy... and we all know how oda loves wanking Luffy at every turn, it wouldn't be strange to see an Oden wank, in the ARC where he is highlighted, not to mention a member of WB and Roger ship, who both highly respected and WB considered as a younger brother "not son"
A man, who WB himself claimed that Oden is a man who should command his own crew... So basically the wank is justifiable
