There is some enjoyment in sin. (That is why people indulge in them.) After some time even this hideous joy is lost (and the person commits the sin by force of habit. This is called joyless sinning (gunah belazzat).) Hazrat Thanwi (RA) said that a person thinks that I shall scratch only once and then I shall stop. So is the case of sinning.
