this recent one is great ! I'm so sorry that this isn’t exactly prophecy-hero-kills-FL, but it’s very close in themes, I think ?? (fate, betrayal, regression, choosing a different man & revenge)
https://www.mangago.me/read-manga/the_dawn_that_twists_your_neck_lua_comic/ the story goes like this,
FL is the low-born concubine’s daughter whose life is repeatedly ruined by the crown prince across three lives.. betrayal, being framed as a traitor, political destruction blabla and she met this ML that swore loyalty to her (she planned it but they soon get closer), and he was like "whoever that bastard is, I'll kill him for you" when FL was having a nightmare about that shitty crown prince, i was blushing like crazy, it's still new so the revenge aren't fully there yet but it seems promising
Tysm!
Is there a story that's about a FL falling in love with the prophesized hero who will save the world, but is killed by them because it would save the world. When the FL is reincarnated, she is subjected to the same life of falling in love with the hero but actively goes against fate and goes to and falls for the villain instead and takes revenge on the hero?
Anything that's similar would be fine! The genders could even be switched, could even be mlm or wlw
