Well...First, you should check if the problem can be solved without a spell/curse. If you find that it can't...Then and only then should you cast.
If you want a spell...Do you mind giving the Justice Spell I posted a try? I would like to hear feedback from someone else who tried it on how well it works. But honestly, I would recommend making your own spell. A spell made by the caster is more effective than a spell made by someone else.
