It's a theory called the "Macdonald triad"

From Wikipedia:

The triad links cruelty to animals, obsession with fire setting, and persistent bedwetting past a certain age, to violent behaviors, particularly homicidal behavior and sexually predatory behavior.

I was being facetious in my comment.

This theory has been controversial, and I don't think it is universally accepted.
