Working on one of my stories and having some trouble sticking the landing here at the end. Basically this villain has tortured the MC both physically and mentally throughout the story by putting him through horrific challenges (think kind of like Saw but less gore porn). MC finally has the advantage over the villain. The villain doing all of these things to my MC has changed him going forward. He'll be a much darker individual now. I want it to kind of center around that. However, I cannot let the MC kill him because he hasn't crossed that line yet and I have plans for when he will. I want the ending to seem like although he died, the villain won. I currently have one thought out but I'm not really sold on it. He taunts the MC about not being able to save his fiancé. The killer was right in front of him and he let him get away. Then later on the killer dies in front of the MC before he could exact any revenge. My villain says the same will happen here and proceeds to jump off a building and laughing to his death. Would appreciate thoughts and ideas.
