Seriously in over my head

This is a dark story about a boy name Harry. He seems to have made the only option to live resulting in a messy obsession. Harry is a serial killer. He can't help it though. No he isn't one of those kids who was abused or grew up with pain and killing around him there's just this impulse that urges him to do it. He loves to see the sticky red stuff ooze out. Yet he can't seem to do it to himself so he does it on others.
