i think all of acacia's disciplines and don slime met deaths fitting for them.



ichiryuu died because he wished to help his little brother and he did not fight in order to kill.

don slime was too proud of his disasterous techniques and his uneatable body, but met his demise because as his techniques and being was devoured by another appetite.

jirou died because he did not know the side effects of techniques he keen on and his master taught him in roughest way. if he were to be more careful during fights,did not rely on damage knocking and could avoid damage without bracing it with knocking and would test effects of damage knocking on some opponent he would have survived.

midora kidnapped many chiefs of the world so that they would cook for him. in the very end he was the one being cooked at the hands of a cook.
