Radagon is such a fascinating character, as while we know that his leaving of Rennala was coerced and that his and Marika's goals did not align, he DID become Marika and we don't quite know how "coerced" their relationship truly was. For all we know, he saw the second marriage as just part of his duty and may have actually loved Malenia and Miquella, maybe even Marika in his own way.
