To create guilt, all that you need is a very simple thing: start calling mistakes, errors - sins. They are simply mistakes, human. Now, if somebody commits a mistake in mathematics - two plus two, and he concludes it makes five - you don`t say he has committed a sin. He is unalert, he is not paying attention to what he is doing. He is unprepared, he has not done his homework. He is certainly committing a mistake, but a mistake is not a sin. It can be corrected. A mistake does not make him feel guilty. At the most it makes him feel foolish.
