State of shock

Another sad day. We know who the Virginia Tech killer was, a student,
a senior, who would have graduated soon, but instead sent himself to
the depths of Hades after destroying over 30 families (including his
own). And now on the various news websites we see the pictures of
some of the victims, the happy faces of lives ended so suddenly and
ruthlessly. Professors, students, men, women, Virginians, Americans,
even citizens of other nations. It simply makes no sense. We could
beat our heads against a multitude of walls and never comprehend
what on earth was going on in the shooter's mind as he shot....and
reloaded....and shot again....what was going on so bad in his mind, in
his life....that made him do this? Cannot comprehend...impossible.
