When you use magic you must do so responsibly. Magic is like a pebble tossed into the middle of a pond, it makes ripples. People will ask you to do many sorts of things on there behalf which may or may not be in their best interest. Lovesick people will ask for love spells. Now I dont personally indorse the use of a love spell or an attraction spell, but they are out there. What you must keep in mind is this though if you choose to do love spells. When you manipullate the fates to bend to your choosing you may also be manipulated in another lifetime. For example if you bend the fate and catch the eye of the one you love, in another lifetime they may do so to you, only they might not be so nice in that life. Another issue is the one of binding. There are times when an individual may be doing harm to others and refuses to stop. The question to consider then would be "Is this individual doing such a great amount of harm that it would be for the greater good to stop him at the risk of the three-fold law?"For whatever you do will come back to you 3 times good or bad. Is it worth the risk. Be positive that what you do you would wish to come back to you three times over.
It can be tough but just think back to the Charge of the Godess ,written by Doreen Valiente a leading pagan author , "only in self defense" or use a binding only when ones person is attacked and only to defend ones self.
