Worse than animals.

I will never understand how human beings can willfully and purposely cause pain and suffering on others. The fact that these people did what they did and probably aren't even giving it a second thought disgusts and saddens me to no end. It makes me sick to think that humans like this exist in the same civilization as I do, when their behavior can't even be described as being animalistic. Animals don't do things like this out of spite or hatred or revenge. It is simply disgusting. And I hope that someday they are haunted by their actions.
