Typically, a sociopathic (serial) killer will display three symptomes that are most recogniseable to be charactertraits of killers, also known as the homocidal triade. These three symptomes will display themselves mostly during childhood. They are:

-Starting fires

-Bedwedding

-Cruelty to animals/animal torture

Besides these, there are external factors that can contribute to people becoming killers, for example an abusive household, drugs or alcohol problems and a passive or absent father/mother or both.
