Same can be said to SS :/ also I can't see Sasuke dating Ino since they never shared a moment together in all the manga, Sakura and Ino love for Sasuke was just fanboyism and infatuation initially, at least with Karin, she fell in love with him because he saved her.
Yes both can be said about SS, I can say Sakura also fell in love with him after knowing him better in part 1 or after the thank you scene when he was leaving but again there is no any reason to a girl keeps loving a man who tried to kill her
Karin's obssession is not any better than Sakura and Ino's, it's even worse, like the sorry scene is basically : the dude literally puts a hole on her chest wihile having a smile in his face and leaves her to die and then later says a cold "sorry" with no signal of trully regreting what he did and what Karin does ? she just jumps into his arms like nothing happened at least Sakura didn't accept easily Sasuke's sorry
They shared a few scenes in part 1 and in part 2 Ino kept loving Sasuke, it would still make more sense than Sasuke being married to someone he tried to kill
