It is indeed a horrible incident and a tragic waste of life. I really feel badly for those victims.
Some are asking the question whether or not the shooter was imitating a scene from a 1986 Batman comic book.
Whatever the motive, the shooter is really a sick individual.

The problem is just there isn't enough good decent parenting. Kids are corrupted with evil shit from watching violent videos games. Mario was the beginning now days there are so many kill the world games that is becoming scary.
