That's really inviting the real issue with Abby. They designed a story for people to hate her, with the expectation that she'd grow in you and you'd sympathize with her at the end. She literally looks that way through a whole game for the big reveal at the end when you see her.

It's a post-apocalyptic setting, and she's the only one jacked. It would have taken all of 30 seconds to show an active dairy farm, a weight gym, and other people also jacked. Bulking up muscle if you don't have the resources is not a wise thing to do. Turns out there's a "blink and you'll miss it" gym. Very possible to not see it if you don't rotate the camera to look. Still, a single person walking up looking like her (jacked), to be VERY explicit would have gone a long way.

If the second game had started at the end of the first game, from the perspective of Abby (basically take the one flashback and make that the start), and then you move forward in time bouncing between Ellie and Abby, giving players time to learn about Abby, that would have changed a lot.

Instead we are forced to play Abby, who has an unnecessary sex scene with her friends (Mel) boyfriend (Owen), who immediately kills Joel, who appears to be wasting resources on a selfish revenge plot, in a game with a story was written by writers who saw Momento + GoT and thought they could pull off clever writing (they couldn't). And at no point is the player given any agency, especially at its ending.

Abby sucked, because Naughty Dog set the character up for failure.
