While it is important for him to be studied and no effort should be made to hide what he did, what he was, or why he did it, I personally do not intend to discuss him. He should be consigned to the dungheap of history.
It’s a waste of time to study the shooter. I refuse to accept the excuse that he was mentally ill. He was just plain evil and he met the fate appropriate to the evil.
I will, however, pray for the victims and their loved ones.
