Sickening. Horrible. It is said that the human spirit/soul was not designed to be able to be comfortable in the presence of brutality. And that the spirit requires compassion within itself and in it's surroundings to thrive; the opposite is abhorrent. If people are capable of the kind of behavior (and worse) that this mentally ill teenager shows, they have truly corrupted mind that is filled with evil thoughts and feelings. If it were up to me what to do with that kid, no one would ever have to coexist with him/her ever again.
