Know of any historical tales in which a man kills the woman he loves as a sacrifice in the name of duty, religion, etc.?
I'll take mythological tales too, but for the purposes of the novel I'm writing, I'm hoping there will be a story from history that can be a good jumping off point for me. Preferably something B.C. as I'll be using future time periods as well. She does actually have to die to further the story, and I'd like to avoid familial ties (brother/sister, parent/child) being the relationship between the two characters.
Perhaps this is an odd request, but this seems like a site full of knowledgeable people, so I thought I'd go ahead and ask. Thanks! :)
