Sakura's intentions in her fake love confession came from a good place with Naruto's best intentions on her mind. She was not intending to be manipulative!!
It annoys me so much when ppl call Sakura so many names for this scene even though it's been more than a decade since this chapter came out, I'll try to explain her motives behind the fake confession becuz y'all just can't seem to understand how a teenage girl in her shoes going through mental and emotional turmoil would react and yes she was going through serious stuff, had her village destroyed, sensei in a coma, her "true love" (i say that term loosely) betrayed everyone and is has a bounty on his head, and she was guilt-tripped, gaslight by two "friends" who btw everyone in the fandom glosses over even through they were responsible for triggering this entire conflict in the first place!!
She had her reasons she didn't purposely try to play with his feelings and manipulate Naruto, she wanted him to forget Sasuke and protect his life cuz she knew how reckless Naruto is an would get himself killed for the sake of others, so she lied abt her own feelings becuz she got gaslighted by Sai and Shikamaru that he was only bringing back Sasuke becuz of the promise he made to her so she felt it was her **RESPONSIBILITY** to clear up the mess she thought she made not understanding that Naruto wants Sasuke back cuz he thinks of him as a brother regardless of the promise he made.
All in all, Sakura's reaction was understandable given the emotional turmoil after finding out Sasuke became an International criminal and the target of a manhunt since he affiliated himself with the Akatsuki as well as being emotionally manipulated by her "friends", was her approach wrong? yeah definitely but her intentions? they were pure and came from a good place with Naruto's well-being as her priority over her feelings for Sasuke, she was this close to actually killing Sasuke since she thought it would free Naruto's burden but just couldn't cause freaking Kishi just can't let her get over him becuz if would make her a "bad" woman.
