First point is to question, and not trust the supernatural just because it has power.
Many people talk about religion, or belief in terms of just picking some way to believe.
I think we should look at what belief system teaches what we also think and feel is best, because God gave us a heart and mind.
So if a belief system also has views that make sense and you feel are correct, then that is what you feel is best. If one has views that you disagree with, then you ignore that view.
So the bad cats you speak of in metaphor, yes ignore them. But how do you know which spiritual things are good and which are bad? By the fruits, by how they effect the world people live in, and how an individual feels the world should be effected.
Many people when they see power, just think it is right because it has power, and get trapped and tricked as you mention. So besides just power, something must also have a set of values and a foundation that is the things people choose to want to believe are the better ways.
If it is of love, and better conditions for more people, and it is not about hate or the other bad things, then I think it has good in it, and then if it shows that it helps people to find a better way, then it will show those things also.
However I agree that the same person can do both good and bad, sometimes in the same expression. So you also have to find what parts of things you like, and want to see and learn from.
So yea, some things are bad, but some are good also. There is a group that says all things of spirit are bad, then they try to hide things of the spirit that share love also. And I agree some are bad, but when you hide all things of spirit, you help the bad side, since it does what it does in secret.
Anyway, trusting something is not the point, it is asking if there is good, and better results for most people, and how do you choose to see something. Or, do you see the rose, or just the thorns.
It may be you were being serious, or just said what you posted for another reason, so no hard feelings, but I disagree with saying anything is all one way or another, but agree people should feel and think to avoid the views and ideas of the things you mention.
Also know that light has power over darkness simply by shining its light, so do not fear them, they only have power if you give it to them. I think it is better to just find what is light based on your view and how you feel and think.
Is she smiling?
Edit: There is a distinction that is interesting. The source of good is not always easily seen, because they are not looking for credit but just want to get the better things done, while the source of bad hides in secret to attempt to avoid justice.
I find that interesting.
