As a nonreligious person I just don't agree with that statement at all. The idea that there is some sinister force flowing around the earth is bizarre and medieval.
More accurately, non-insane people behave as they do in order to achieve a goal that they think will bring them happiness. Unless there is a motive of revenge or bad PR then there is no way that the degree of vandalism done in this case could possibly make the vandal happy. Anyone who would go to great lengths to destroy all traces of a stranger's personal property is mentally ill.
Mental illness has a material cause, not a supernatural one.
1. Drugs
2. Thieves who knew/thought they'd get away with this, thus also wrecked the place (Occam's Razor will suggest this)
3. As you mentioned yourself - revenge or bad PR.
The person who did this is mentally unbalanced, and needs help.
