The repetition of the ideas of hate and love here emphasize that his feelings had changed completely. The abstract nouns "hatred" and "love" can be left untranslated. Alternate translation: "He hated her even more than he had loved her" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
You may need to make explicit that the words "love" and "loved" here refer only to sexual desire. Alternate translation: "had desired her" (See: [[rc://en/ta/man/jit/figs-explicit]])
