You clearly have no concept of the awesomeness that is tobirama. Lord tobirama will forgive you if you accept him as the one true king and regularly donate a percentage pf your income to his churches.
I think theres levels to what you're saying. Like you have to destroy the persons body like what obito did to hiruzen in order to not move. A zombie will move with a stab or something but when you seperate his head and body and legs whatever, theyre incapable of doing anything. He would have been able to move of his torso and face were blown of because he couldnt see kinda. Idk if im explaining it good lol
