There's somebody out there that is watching this and hasn't done that – hasn't killed people, and wants to, and rages inside and struggles with that feeling, or is so sure they have it under control. They need to talk to somebody about it. Trust somebody enough to sit down and talk about something that isn't a crime; thinking that way isn't a crime. Doing it isn't just a crime, it's a horrible thing, it doesn't know when to quit and it can't be stopped easily once it starts.
