Huh? The ambiguity was if Joel did the right thing getting Ellie back at the cost of possibly never getting a vaccine developed.You said it ended the ambiguity at the end of the first game. That's not true considering Joel never told Ellie he regretted his decision and Ellie still would've sacrificed herself for the fireflies. If Joel ADMITTED he was wrong, then you would have a point, but he didn't.
It was the right thing, the Fireflies were morally in the wrong and were going to get them both killed.
What decision you talking about? He never regretted saving her and he reaffirms that in TLOU2. If you mean the lying then yeah, he might've regretted that specifically but that's hardly the main component of the ambiguity of part I's end.
The issue is that the player gets no say in how Abby's crew end up but still gets quasi-lectured about how bad killing/revenge is each time.Did you even play the game?
It was never Ellie's initial intent to kill Nora, Mel and Owen. She just wanted them to give up Abby's location.
To Nora: Tell me where she went and I'll think about letting you go.
To Mel and Owen: You guys can survive this I just need her.
The only person she kills right away was Jordan and that was to protect Dina from being killed.
The WLF are also trained to kill on sight, and its not even her intent to kill anyone (other than Abby).
