Well, of course. However, you can find online many spells they use for personal gain, such as love spells, money spells. It's completely against the basic law of Wiccans. You have to give, not to take. Because the trick is, the more you give, more will be given to you by universe. You can't just ask for money and do bad things to others.
I mean, you can probably with some dark magic stuff.
