Killing is not right, but some "serial killings" are actuallt done by hired hitmen, the guy your mum knew might of been like that. A job is a job for them. Taking human life is not a good thing, but most of the soldiers I have talked to are kind and helpfull, they pretty much do the same thing. No matter what people say, that sniper and the soldiers are the same, the soldiers kill people, that guy killed people, its all in the contract. That may sound harsh, but that is the way it is.
