Only, without tactical intelligence she would never be able to destroy 3rd Kazekage puppet. When she charged at Madara she tried to make a room for Naruto and Sasuke to land a hit on him. Tactially-wise it wasnt a stupid move at all, Sasuke tried to make use of it. Yes, Naruto told her to wait, but the guy has feelings for her so its only natural.
Listen, she was planning to trick him and kill him. She didnt want to put her teammates in danger, so she did what she did. If Lee and KIba started to fight with Sasuke, what do you think would happen?
Quite a lot. Sometimes her emotions gets better of her, but thats completely natural. Tsunade alsmost betrayed Konoha becuase Orochimaru could revive Dan and Nawaki, Hiruzen couldnt bring himself to kill Orochimaru, even though he knew that he killed several Konohas shinobis and civilians for his experiments, and he could pose a great danger for Konoha in the future.
