Did (past) Nebula want to...? So, I'm watching endgame yet again, and I just noticed that Nebula kills her past self after past-Nebula says Thanos won't let her change and turns her gun to Gamora. If Thanos wouldn't let her change, i.e. let them go or help them, and she doesn't want to hurt them, then isn't her only option death (from her POV)? So did she deliberately turn her gun to Gamora knowing that Nebula would kill her? Or did past-Nebula simply fear Thanos more than she cared about Gamora? But then why not kill future Nebula first if she's already aiming at her, especially knowing that Nebula has a gun in her arm?

Maybe a silly question, but I wanted to see what y'all think. Thanks!
