Kakashi and Sakura's Standpoint....

[Jnaru]

She may have loved him once but she never understood him, his feelings or the reason he did what he has done up to this point other then Naruto...

Yeah Sakura had no idea wat was in sasuke mind..... Only naruto knew him...

And Sakura still cldnt kill or hurt sasuke even if she wanted too, she is blind in love..
All through the war arc she was singing sasuke-kun , so she cldnt help naruto,
only kakashi can help naruto in fight
