They all helped someone or something.

To me, Leo can stay as dead or when Jason and Piper were fighting with Gaea they could've died. Hazel and Frank could've died when they were trying to save each other. They were the best options. Hazel was tecnically undead and Frank's life is tied to a stick. I think, if Percy and Annabeth were dead, fans go mad. But Percy and Annabeth could've died later or in the end of the story.
