I can rec you a fic: "The Winter Army" by gaudior. It is on ao3 and one of the best fics I read in 15+ years of fic reading.
It features most things you are looking for. Bucky developed multiple personalties and the avengers are trying to crack the winter soldier programming. It is more a ploty drama than porn, but the "murder while sex" atempt is there.
