@Psychronia you're exactly right.
@Mahtan doesn't seem to get this for some reason though. The only thing I would say though is breaking the political marriges is a 'big deal' but not really frowned upon it seems. We've seen nor heard of no repercussions for that and everyone seems to be okay with it in the end, so that leads to me to believe it's not 'unheard of' and just somethign they really need to think about before doing.
I would also like to add there there are two moralities at play when any action is taken. The morality of the person, and the morality of the action itself. If you're unaware of the consequences of an action, you could still be a morally good person, because you didn't have ill intent, but the action would still be a morally bad action. This however does not make morality 'subjective' as some people think. At least not when we're talking about it on a binary since of 'bad' or 'good'. A morally bad action, is an action that causes more harm than good. It doesn't matter what people know, that only effects -perceived- morality, but not actual morality.People's perceptions of a person are not absolute, and people confused 'morality' with law, but morality is about the base principles of the action or person, and so morality is only applied to the whole of information, not to partial.
So no Heronia thinking that this is her 'right' does not make her actions morally just. That's like saying the nazis were just because they believed they had the right as a superior kind of human. Delusions of grandeur do not change the morality of one's actions. It just makes that person either mentally unstable, or an idiot. And it -might- excuse them if they are mentally ill enough, but it still doesn't change the 'morality'. Morality should not be confused for "Will they be blamed in court" That's why 'law' is not called a 'moral code' because they are separate things.
And for the record, how Bertia treats Cecil is morally wrong too, because she, like Heronia is ignoring his agency. Disregarding someone's freewill, is morally wrong, plain and simple. Be it Bertia or Heronia, be it if they're crazy or sane. All that chances is if they are punished and what it is, but it doesn't change the morality of it.
A great example is the 3 other heroes from Shield hero. They treat the world like it's a 'game' and people die because of it, and lots of damages happen, and lots of harm. You can't sit there and say they were morally right because "They thought it was their right to act that way"
