You could argue that Enisha is just as bad as them. She didn't spare the girl and her family out of compassion, she did it because it'd be annoying to deal with the aftermath. I mean, she is an adult archmage on the inside who has lived for who knows how long so of course she's a bit jaded, but it puts things into perspective when her thoughts show just how uncaring she can be for the loss of lives. It also shows just how well she fits in with this family.
@Svelandria Uh...no. Why she chose to spare Illiosa is far less important than the fact that she did, and reigned in her brothers in the process. Action and consequence are always more important than intention.
Now, if she chooses to backstab Illiosa at a later date, then you have an argument she's just as bad.
That marquis girl will be a real pain soon. Also how will the princes marry if they cling to her too much...better yet will she ever get married hahaha
