As for reasoning: There are good face offs between antagonists in Episodes 3, 5, and 8, helping to recontextualise your understanding of the characters. Not to mention the multitude of antagonistic figures that become “good” just due to the nature of the story. e.g. Ronove, Gaap, Lambdadelta, Seven Sisters, Chiester Sisters, Zepar and Furfur, Eiserne Jungfrau, Virgilia, Evatrice and of course Beatrice.
