He tried to kill her notably twice; in an altercation before the war that involved Hebi/Taka, and again during the war, but I forget exactly when. Not to mention he's just never been particularly kind to her, aside from when leaving the village and opting to just knock her out rather than let her get involved in his and Naruto's fight (still not really right of him tbh). She wouldn't have been much help in her emotional state at the time, and deciding which side to really be on would have torn her apart- not to mention this is Pre-tsunade training Sakura.
Sasuke has been....a challenge, when discerning his emotions for anyone that wasn't Naruto or Itachi, though. I have never, and still probably wouldn't be able to find one solid example of positivity in the SasuSaku relationship by looking through the Uchiha's eyes. I'm not even sure I could find anything genuinely kind from Sakura's p.o.v either, and I hesitate to talk to shippers about it because they see through a rosey lens, as it were. If anyone here in the FC can pipe up and perhaps give supporting evidence calmly, i'm willing to have that back-and-forth.
Sarada's existence is......purely just for the sake of continuing the story, I think. Sure, Sasuke spoke of reviving the clan at some stage, but I think he meant it more in the metaphoric way of returning honor by clearing the name. I have some serious doubts about whether or not he ever actually intended to be a parent, and on that, even stronger doubts that the he has any confidence in his parenting ability (or obvi. lack thereof). At the start of Boruto, it's my understanding that he has so little knowledge of his own child that he doesn't know what she's supposed to look like and almost kills her. Dad of the year, ya'll.
No, he doesn't deserve that forgiveness, but Sakura, as a character, shouldn't be getting used as the one to dole out that forgiveness either. Kishi did them both dirty, and Tbh I could go on for miles about how Broken Sasuke and his "Family" really are.
Oh and You're welcome, dear. Sasuke has always been fun to pick apart for me, so if ever you want me to try to explain something from his prospective, i'm willing to give it shot. xD
