I think there might be something to be said about the difference between the logical aspect and the affective aspect of a particular moral belief. I can feel that something is bad despite believing on a rational level that it isn't, and vice versa - when I was vegetarian, I believed animal suffering was wrong, but I didn't later feel bad about eating meat.Do you really feel that you're morally bankrupt because of the way that your eating habits changed?
A little bit. Like I said, the reasons I went vegetarian (and subsequently vegan) never disappeared - I still believe that the suffering of animals for the purposes of human consumption is bad. Somewhere along the line I just stopped caring, or lost my conviction or something, and I'm not particularly happy about that. Particularly so because I'd generally assert that all people should be mindful of what they do, and here I am ignoring my own moral dilemmas.
