Did he not run? and go on to be a marine, make his promise to luffy before zoro was a character, have oda say they're destiny linked? You can't just stand up to akainu, have the ambition to become an admiral, get trained by garp and not have it, if you think bb who was like 30+ year old screaming to wb to not kill him to have coc then let the same apply to koby
Lol it doesn't matter if an admiral has shown coc all that matters if it's garp shows it's then it wraps
