Funnily enough, I think the answer I just wrote a few moments ago in response to How can I cut through the negativity of backstabbing coworkers following my promotion at work? would apply exactly here as well.

Yes, he is attracting it (as you've noticed) but the underlying cause of what's causing the attraction may be something completely unrelated to the subject of the violence itself.

It is quite possible, for example, to be so upset about, say, about a romantic relationship not working out that it creates the same emotional response within you as, say, your car being broken into and so you find your car repeatedly being broken into, until you clean up the vibrational cause.

And that isn't a random example either because it happened to me many years ago. It took me 3 car break-ins within the space of a couple of months (after never experiencing any breakins previously ever) to spot the pattern :) When I found a way to feel better, it all suddenly stopped.

Our physical manifestations match our emotions, not necessarily the subject of our negativity.

This is my answer to another question,but it is valid here too.
