'I want to see if they still dare order my family at that time.' thought Angus.
Angus rarely used his authority and rights as a high noble. He also didn't like to abuse such a backward aristocratic system. However, it doesn't mean he will follow strict orders unless they are indispensable.
Previously, Angus may have advocated the importance of following their law to maintain order. But it doesn't mean he will always follow the law and order. The law and regulation is still made by people and he knows how flawless people can be, especially the corrupted one.
There will always be some mistakes, be it in the execution or in certain cases. Angus' true belief is still about Consequentialism.
He believes every action has its own consequences, whether wrong or right. As long as someone can bear the consequences, whatever they do will always become right.
