I feel like the judgement of the prince is way to harsh (especially using the anime after credits as evidence. Who knows what the time gap is, and just because they don't show mourning doesn't mean it didn't happen). Especially blaming him for her own actions in taking the knight, and calling him "cold" when he's been anything but that, really. Honestly, the knight feels like a much worse person. He's a racist because "Its ok if my dad tortured people and butchered families, but its evil if they do it back."

I'll just chalk it up to an incredibly biased FL, which makes sense.
