For many people, sugar is an addiction of sorts. Your mind finds all kinds of reasons why it's okay to keep consuming it, despite your will. This is the concept of bargaining from drug/alcohol treatment.
Is it better to go cold turkey or cheat once in a while? If you have symptoms of addiction, then moderate use probably isn't going to work for you. There's an argument that allowing yourself to indulge occasionally keep you from just binging and ditching the diet altogether. See 'bargaining' above. Besides, once you're off sugar for a few days (2 to 10 days), the cravings decrease substantially. You just don't want it that much anymore. People resist that idea but they haven't put it to the test. That is the addiction talking.
