It was something like did the doctor or Marlene have the right to decide if Ellie should be sacrificed for the cure?
I mean "rights" in the context of the world they live in can get pretty complicated. This is a world where no one would bat an eye at a teenage making adult choices because kids gotta mature rather quickly or die.

The fireflies were not owed a immune kid so they could do test on, but what they were doing was understandable in the context of the situation they were in.
Quite frankly, rather or not they had the right to take her life is irrelevant to the story in the game. From the perspective of Abby, her father was the fireflies best chance for a cure and his team of doctors were killed by the man they hired to deliver Ellie. In the first game, throughout nearly half of the game Ellie is just a payday to Joel. From the fireflies perspective, he could have taken ellie for multiple reasons, what if he took her cause he felt he could get more somewhere else for an immune kid?
Abby doesn't know the reasons behind Joel's actions. To her, Joel's just a scumbag who reneged on a deal and slaughtered a bunch of doctors working on a cure. That's a damn good reason to want to beat his ass to death from her POV, whether or not her father had the right to take ellie's life doesn't matter, Abby's reaction to Joel made sense considering what he did FROM SOMEONE ELSE'S PERSPECTIVE.
