Do you think Horace Danby was unfairly punished, or that he deserved what he got?
According to me, Horace Danby got what he deserved. Though, he was not a professional thief and the robbery did not benefit him in any way, he had robbed people before as well for the mere sake of purchasing rare and expensive books. A thief is a thief: no matter what the purpose is, how much the amount is and who the person being robbed is.
