Any recommendations where the mc is a villain? I mean villain villain. Not the cute roman...

https://www.mangago.zone/read-manga/i_m_the_strongest_boss/ (overpowered mc dungeon boss)
https://www.mangago.zone/read-manga/the_fangs_that_pierce_the_heart/ (Demon taking over a girls body, actually evil)
https://www.mangago.zone/read-manga/brutal_satsujin_kansatsukan_no_kokuhaku/ (Mc is a literal psychopath)
https://www.mangago.zone/read-manga/maria_no_danzai/ (mc is a devastated mother taking revenge for her son’s death, in a messed up way)

Hope I helped!

Thank u!
