gaara is not screwed up cause his mother got killed she got killed when she gave birth to him, he is screwed up cause he got shukaku inside of him and havent gotten one nights sleep in his whole life. you can say that he is a walking corpse or something. and neji isnt really screwed up he is just arrogant and he is lying to himself... sasuke uses the "my family got killed thing" as an excuse for him to seek power even if its bad.the gaara and sasuke are screwed up but not cause of their families. and i dont think itachi is all that bad there has to be some other reason then to test his power for him to kill his family. i think the uchiha clan was fucked up sorta like sasuke and wanted power at any cost and itachi was born sort of as a black sheep he had a tremendous amount of power but didnt wnat to use it as the rest of the clan wanted. so he killed the whole clan exept sasuke casue he couldnt kill a child.
