What kind of people are willing to undertake such dreadful business as murdering innocent women and children?

I think maybe people who are not so confident in themselves and think that they are doomed to a terrible future and maybe when they had their education they didn’t do so well so they just decided that they weren’t good enough to be anything but the lowest job – which would be killing other people for a living. I also think that very extreme people who want to be in the good books with powerful people, who are sometimes bad people, would want to do it. People who have a lot of power usually are more power hungry and so I think they would want to tell people to do their dirty work and people who want a lot of money and want to be in the good books with the power hungry people would want to do the dirty work.

What kind of society produces such callous killers?

Ones where maybe there isn’t as good education and maybe places where parents put a lot of pressure on their children to make a lot of money, so the children grow up thinking that they have to find the quickest and easiest way to make a lot of money.
