I don't necessarily agree with nicknames elevating the status of killers. People still call Ted Bundy, Jeffrey Dahmer and Charles Manson by their names and it still has the same effect. At the end of the day they get off on the attention they get - and they're given plenty.
What would be ideal is if people just stopped talking about them altogether- how they were bought up, their motivation behind the killings, the televised interviews, the movies, the disturbing groupies who write to them and profress their ever-dying love. However, that's never going to change - people will always be morbidly curious about these things.
I think instead we need to hear more about the victims/survivors (at least the families of victims and the survivors who want the details out there). Ignore the person who did this altogether and let the law deal with them, focus on the innocent people who have suffered instead.
