Those of you who put Sakura are stupid. She has the strongest will in the Manga.
Will of Shanaroo >>>>>> will of fire
Lmaooo she fought sasori , while poisoned , on willpower alone.
Sakura's will in stronger than narutos and sasukes.
Sasuke is the only person who has power over her will because she loves him,
And the funny thing is , in the chunnin exams , part 1 Sakura displays everything to counter your claims of her being weak willed.
Resisted Ino
Resisted genjutsu
Fought through pain to protect her teammates
Wasn't intimidated by ibuki
Stood face to face with gaara, with a kunai, no hesitation or nothing , to protect sasuke
