as we know , every yonko in one piece represents a sin from the seven deadly sins, whitebeard was the pride sin and died because of his sin , big mom is the gluttony sin , i think she will die by eating another devil fruit ( by mistake of course ) by eating a df user or eating an actual devil fruit , and i think that this will happen for the other yonkos , blackbeard will die because of his greed , but kaido I don’t exactly his sin , may be the envy , what are your opinions ?
