Hello, I've made one of the chapter's the antagonist's POV, right before a big battle. I wanted to show a bit of how his kingdom and people lived, since we've only been in the protagonist (and his allies)'s kingdom and culture since the start. While I've done that, I'm finding it hard trying to justify their attacks on the enemy. He is the grandson of a man who came to Britain to "help" a British king before slaughtering every single politician of that King's government and declaring himself king instead. The antagonist and his brother both think of this usurper as a hero and great man. I'm really not sure how to portray the antagonist's emotions and thoughts regarding the enemy.
