While some people deserve to be killed once and for all, I always say that you must give someone a chance to repent of the bad things they are doing. If you don't have the courage to tell them to their face that they must stop, you can always give them the hints to show that you know they are trying to harm you. If they don't take heed of your warnings, then you can go all out.
With regards to money spells, you need to approach them with a high level of clarity. Decide beforehand where you want the money to come from. For instance, do you want it to come from the lotto, a promotion, or from a business? Clarity is a currency when it comes to spells. Never be driven by greed; always ask the universe in moderation.
