Evil walks among us

Sometimes I think I cannot be surprised by the awful things I read about. This story is one of the worst. I find it so scary that people can do this to each other, that someone could walk up to another person and throw something flammable on them and set them on fire. Then what made it even worse that one of the boys laughed.

Where do they come from. Who taught them right from wrong - or maybe that is the point - nobody. If they can do something like this in their young teens, what can we look forward to as they grow older?
