alright lemme sort somethin out here.
in Bleach, when a normal person dies, they go to soul society and live a sort of "second life". If someone is killed or dies of old age in soul society, they ARE REINCARNATED ON EARTH...with no memory of their former life.
So yes, all of the damn shinigami ARE IN FACT risking their lives in combat.
read the fucking manga before you post dumbass comments.
