Granted, I may never have looked around too hard, but I don't know that I've ever seen people playing TLOU and intentionally faceplanting Joel after he decides to save Ellie the way they do Abby when she wants to kill her. That may not be the most scientific measure of whether Player POV is all it takes to get someone to come around to the motives of a character, but it's worth noting.
And again a lot of this comes down to structure. Much like TWD has tried and mostly failed to really accomplish a "face turn" for Negan, because of the brutal depravity on display when he was introduced*, structuring TLOU 2 to preordain contempt and hatred for Abby was a mistake. If player after player are reacting to the transition in POV to Abby with disgust and annoyance, you are not a clever writer and the player is not a dumb philistine. What's actually happened is you have failed to even set a predicate for the player to even give a damn who Abby is or what motivates her and just forcing them to sit there while you make the argument for ten hours. And, unsurprisingly, the conversion rate is pretty mild of people who arrive back at the theater thinking "oh, well, yes, I'm okay with this and I'm not a willing participant in this boss fight" instead of just stuck doing it because it's on rails.
By the time you reach the theater at all as a player, you should be confused about what the right thing even is, if you really want to bothsides the cycle of revenge.
