I have a theory regarding the curse. Is his(MC) bad luck attributed to the curse he has!?!. We all know that the hidden being called these Grimms as spawn of abomination. A being is called Abomination when they shed innocents blood with their vile wicked methods. When the spawn of abominations curse has gained sentience in MC body, his luck aspect was reduced as the world is probably not able to differentiate between both of them as both of them present in same body(MC body). As for why grimms get their luck nerfed. It might be because they are such evil beings and that is the reason they death count will always be more compared to humans. Any say?
