You see that? Sakura knows she’s no match for Kaguya and yet she’s itching—trembling to attack her because she hurt her boys. And I know she’s not shaking because she’s not afraid because Kakashi said so in the panel. He’s worried that Sakura might let her emotions get the best of her and attack Kaguya as retaliation for Sasuke and Naruto. Which will probably kill her because she’s just a normal unlike Sasuke or Naruto.

Sakura is willing to attack the Mother of all shinobi/ninjutsu/or something because she hurt her boys. Call it stupid or whatever but that definitely is a long ways away from the old Sakura.
