Same spirits to protect your home and throw curses?

I heard people say you should use different spirits for protection than for cursing your enemies? I wou like to use the same since we have a relationship but…any thoughts?

If you have a spirit you are working with already you may wanna inqure if they can help you with this.

With alot of forces they encompass both sides of abthing for example marbas can cause disease and heal it. Saturn can bind and banish. Ect. It may not always be the case with all entities but asking them would be the most direct route to find out.
