Choice and Consequence of Redemption

What is there to redeem when you kill for a good cause?Nick is a boxer with a taste for blood. He prowls the streets of Hillside City every other night to kill criminals, abusive parents, and such. On one night, he comes across the Doll Factory, a secret organization that sells people as sex dolls. Doubts about his vigilantism come in and he has to decide whether or not if he should keep killing or help people in a more peaceful way. Will Nick kill more or let more people be used as objects rather than people? One more massacre? Or a dozen more victims?
