She's not helping anyone by just punching and healing. She's selfish because she always thinks for herself and not for others. Always hits naruto from the beginning to the end of the naruto franchise. She wants to be with sasuke and do anything to have him. Tried to kill Karin to prove her loyalty to sasuke and then makes up her mind by trying to stab him in the back with her poison kunai. Lied to naruto about she loves him. And she wants to run up ahead and get pass naruto and sasuke because she's "stronger than them".
