empathy
It takes no great personality defect to suffer from scary thoughts.
Anyone can become sensitized at any time, due to some life event or stressful situation. It sensitizes your nerves, making any anxious thought strike almost like a physical blow. This frightens the person, they think they must be some kind of monster to think like this. So now, they've further sensitized themselves into believing this bluff.
Because they try so hard to stop the thoughts from coming, they keep coming back. Can you see how this develops? There isn't much to it really. It's human.
