Everything the Clone experiences so does the user right?, i remember when Naruto fought with his clones he would get bruised, so my point is wouldnt that mean if One of Naruto's Clones get stabbed, Shouldnt Naruto die??
and if you remember, Naruto's method to master rasenshuriken? - he used a 1000 clones to boost his experience! - that means its not just memories that get back at him but also any kind of experience!
