You know, she could have simply talked with him about the case, being honest here would work better than this shit she pulled out her ass.

She was not successful exactly BECAUSE she wanted to use Naruto's feelings to make him change his mind.

I understand her intentions might have been good, but she's telling herself "sorry, Naruto" for a reason.

Imo let Sasuke kill Sakura, Sasuke then feels better and comes back to Konoha. Naruto gets Hinata, Sasuke revives clan by ravaging Karin = problem solved
