Here's the thing: there's a sick sort of comfort that comes from these self-judgments. That's because they relieve us of the responsibility for our own actions. If I decide that I can't give up ice cream because I'm a horrible person-that "horrible person-ness" precludes my ability to change or improve in the future-therefore, it's technically out of my hands, isn't it? It implies that there's nothing I can do about my cravings or compulsions, so fuck it, why try?
