Miguel didn't have a good impression of other creatures. He was born and raised in a powerhouse in the Mainland — a founding family at that. Therefore, it was no surprise he had a sense of superiority over other vampires, especially other races.
Even so, he had adapted well to the outside world. He realized a thing or two: one was that not all parts of the world knew the existence of vampires. The other realization was that everyone in the outside world was far too fragile. Breaking humans was too pathetic for him; it was too low for him.
Therefore, he would rather resort to scolding and lectures before truly soiling his hands.
