I've changed my mind on Black Widow's death, I was talking to a friend about it this morning and she brought up an interesting point. In most films and stories, women tend to sacrifice themselves for their love interests or their children while men tend to have heroic sacrifices for the greater good. Black Widow is a rare example of a female character sacrificing themselves, not for a personal connection but for the desire to do good by everyone.

Widow wasn't fridged to create motivation for the male heroes, it wasn't Gamora's death all over again. It was the inverse of Gamora's death and the more I think about it, the more I like how it went down. It's unfortunate she died but she died in a way that few female characters do, in an empowered and heroic fashion.
