For my story, I am not sure how to end it, as I have several directions I could go. I am halfway finished and the rest depends upon what ending I decide to build into. The story is about a serial rapist/killer type villain who goes around doing what she does, because she suffers from involuntary celibacy, and having to deal with it growing up and all her life, never becoming close to the opposite gender, causes her to take what she wants in order to feel power. The protagonist is a cop investigating her, and the cop becomes her latest rape victim, but survives and escapes. The justice system fails to catch her for him, and he then wants justice himself. There are two ways he can get it. He can try the legal way, but cannot find any evidence legally, thus causing him to go vigilante on the villain, and either killing her, or framing her with illegal methods to take her down. Or he can still play within the rules of the system and beat them at their own game, showing them he was better at getting evidence on her and catching her, than they were. Although because he was one of her victim's would this legally be a problem of a conflict of interest in the investigation though? So he can either come out like Columbo, and arrest her with evidence, the smart, but legal way, or he can come out like Jack Bauer, and get total revenge. Of course these aren't really endings, but more like third acts. Each one would have their own different endings each. Which direction to go do you think sounds better? Or should I combine the two and possibly have the cake and eat it too, or would that go against character motivation? I know I haven't given a lot, but I am getting writer's block on this one and do not know where to go after the first half, in the MC's way of achieving his goal, that would be better for that type of story premise. What do you think?
