" If you have given up your heart for the Tower, Roland, you have already lost. A heartless creature is a loveless creature, and a loveless creature is a beast. To be a beast is perhaps bearable, although the man who has become one will surely pay hell’s own price in the end, but if you should gain your object? What if you should, heartless, storm the Dark Tower and win it? What could you do except degenerate from beast to monster? To gain one’s object as a beast would only be bitterly comic, like giving a magnifying glass to an elephant. But to gain one’s object as a monster…To pay hell is one thing. But do you want to own it? "
