  More to the point might be a worry about special pleading. This is different from backsliding, because the special pleader is the person who makes exceptions in their own favour. It would not be right for most people to do what I propose to do, but I am special; so I am left off the moral hook that others are caught by. This sort of special pleading occurs in the process of making our moral decision; it is not to do with motivation thereafter, as backsliding is. With backsliding I say ‘this is wrong but I am going to do it all the same’; with special pleading I say ‘this would be wrong for others, but not for me’.
