Mr. Clemon can think of a lot of good reasons.

Mr. Clemon down at Alice while confidently saying, "Alice, you have been the best slave a man could ask for, but I have tried you helplessly to a cross, whipped every inch of your body, had my way with every single one of your holes, all while videotaping every second of it. A relationship is supposed to be a fair two-way street, and I am sorry, but after I have done those things to you, I don't think our relationship could ever be fair."

Alice looks away in sadness, which kills Mr. Clemon inside; he never wanted to hurt her. That is why I said what he said. He knows this is the only way she will ever be able to experience true love. After what he did to her, he knows that he could never give her true love.
