Is absolutely perfect in every way, she's right about everything and that's why nobody disagrees with her. This makes her the better ruler and a better person, because she doesn't make stupid choices that piss people off and divide the army. She knows the importance of solidarity, knows what's best for Fodlan, and isn't afraid to take risks to save someone's life even if she claims she only did it out of convenience. How can anyone defend the oppressive Archbishop or her toady King when Lady Edelgard exists?
