Would you consider it bad karma to intentionaly leave someone out of a benefitial spell, Exs. Specifically unincluding someone from a family/home protection spell that you knew was adusive or unhealthy for the family. Or leaveing the local pedifile out of healing rituals at the hospital. Just curious what everyone's thoughts on this are

I wouldn't think so if your protecting the family from that member??

Karma is a balance as well as a judge. I think that if you do a protection spell or healing spell in a group like you did and request that if its for the greater good, so whatever it is the abusive relative or local pedafile will be touched in a manner fitting of their acts. The abusive relative may get anger management classes and recover, the pedofile.... well I have a narrow view of them, so my opinoin don't count on that, but you get my point.

Since Intention is a large part of success with any spell work and if you do not believe the person sopuld have your protection then the spell will likely fail for them.
If you can't mean what you say/do then you are better off not doing it, that is being true and honest with yourself.
