This makes no sense he called oden a brother , i cannot remember how many people he called that .
Are you saying WB had no clue with wano situation his crew was the powerful in the world. This literally makes no sense he was not worried about odens safety whdn kaido was ruling wano.
Kaidos rule as an emperor in the New World. I'm pretty sure started after Odens death. He very could not have been a big name before Odens death, thus Whitebeard not knowing about Kaidos whereabouts. Also, Whitebeard himself was focused on gaining prowess and supremacy in the New World around that point in time.
But let's assume kaido was already a Yonko before Odens death, and Whitebeard knew about it:
- Oden specifically refused Rayleigh's help and the Roger pirates help in general. Saying he needed to handle it on his own.
- Roger would logically tell Whitebeard this, as it's the reason why Oden didn't return to the WBP.
Whitebeard has two choices now:
-> Not give a fuck/disrespect his brother's wishes about his brother's wishes in dealing with Wano on his own.
-> Respect his brother's wishes and have faith in him.
Whitebeard was a grown man into his late 40s and early 50s. Oden was a man in his 30s. I mean they're not children. A grown man will more than likely respect another grown man's decision. Especially if they are pirates.
