I think Endgame actually did a decent job at showing that Nebula has never really been a bad person at all, and all the bad things she may have done in the past, she only did because she was a terrified little girl living in constant fear of her father and the consequences of disappointing him.
Once free of Thanos' influence, however, she no longer needed to maintain the facade of a heartless killer, which has helped her survive until that point, and we got to see more of her true nature, as seen in the gentle way she cared for Tony, or how she seemed to have embraced being an Avenger without hesitation.
