It is of critical importance to recognise that for people who regard themselves as having no recourse to better their lives, the exercise of violence proves an intoxicating surrogate. Shame - despite its origins in the self - is an excruciatingly public emotion. To feel it is to feel oneself a reprobate. Overcompensation through personal achievement is not an option. When a person feels judged - hounded - by the jury that is public opinion, the only way to exorcise that feeling is to eliminate the jury altogether. In the mind of the perpetrator, transferring one’s own suffering onto another human being becomes a viable - almost noble - moral calculus, turning the master-slave dialectic on its head.
