Before answering this question, it is important to remember that the woman - Mrs Drover - does not go willingly with the Demon Lover. In fact, she is actively avoiding this man as we see by her efforts to get a taxi before "the clock strikes," when he is due to appear. Moreover, in seeking a taxi, it is Mrs Drover's aim to get out of London as quickly as possible and to return to her family in the country.

It is also important to note that we do not know for certain that the taxi driver is indeed the Demon Lover who has come to reclaim his bride. If you read the reference link provided, you will see that this scene has also been  interpreted as evidence of Mrs Drover's psychological breakdown. In this interpretation, the Demon Lover may be nothing more than a figment of her imagination.

With this in mind, then, our attitude towards Mrs Drover should be one of sympathy because she is either a victim of kidnap or one of mental anguish.
