On the other hand, Angus didn't need these noble families. He already has enough resources and money to support himself for a few generations. He also didn't need any of their connections. What Angus needs now is a strength that could only be obtained by himself.
In summary, Angus didn't need help from these noble families, but they needed him to help them with many things. Unfortunately, Angus never intended to help anyone except his family and King Leon.
He is neither a samaritan nor a hero who will sacrifice his life and everything for this kingdom just to be exploited by others in the end. Previously, Angus gave King Leon all the modified spells and skills because he didn't want his family and friends to fight a losing battle.
If they end up dying on the battlefield, he wants them to die for winning a battle. This way, their sacrifice will have more meaning. As for how the war went, he didn't care about it.
