I can see what you're getting at, and that is the point of this villain. He isn't like villains who just trash things or blow things up for fun/vengeance.
My reasoning for picking him as the first villain was because it shows the Titans that not all of the villains are doing that they do for kicks and giggles. His world revolves around the person he is protecting, and no gap is to great for him when she is involved.
