How do you know he was mentally unbalanced?

Just because we wouldn't do something like that when we are rational doesn't mean that everyone has been reared with those same values and guidelines.

I read a book a couple of years ago on holiday - can't remember the title, wish I could - written by an American woman whose father had been the target of a terrorist shooting in Jerusalem. She went under cover to seek out the guy who had shot him (he survived btw) and from her first inability to understand the mentality of indiscriminate shootings she began to relate to the people who carried out the shootings and who would rather kill their own sister than have her associate with the wrong kind of person. When one of their family was killed they accepted 'blood money' from the family of the killer and criminal charges were dropped. It made chilling reading. These people weren't mentally ill. It was their way of life, their morals, their standards.
