Sasuke loves his mother. 

When he hurt himself training, it was her he rushed to for treatment and empathy. When he felt neglected by his brother and father, it was her he trained with. When he looked at other mothers and their children, he felt sorry for them because he knew he had the most beautiful, strong, and kind mother in the world. The others couldn’t compare. 

Some hot, humid nights, he doesn’t sleep and passes the dark hours sitting before the toilet, retching to the point of collapse. He does this because his mind is his own enemy, whispering to him that if only his mother survived, the other deaths would have been bearable. Just as long as he had her. If she had survived, he wouldn’t have bothered with revenge.

As long as she was alive, the rest of the Uchiha clan could go to hell.(x)
