The Morally Gray Hero
He does terrible things for understandable reasons — and unforgivable ones for love.
He isn't the villain, exactly. He's the man who does the villain's math and sleeps fine afterward. The appeal isn't that he's good under it all — it's that he isn't, and the heroine wants him anyway, with her eyes open. The best dark romance never redeems him. It just makes you complicit.
