Didn't the high class devils learn anything from the monster incident that happened in volume 10. When not only the monsters, but the devil servants with sacred gears who were converted against their will achieved balance breaker and went on a rampage.

A lot of high class devils were killed during that time. You think that would have at least changed their attitudes. If only a little bit.

They can't simply rely on the old ways anymore.
