Spirit worship

[Peter]

Would Theravadas use spirits to harm others?

A Theravadin is just a person.
Are there people who would try to use spirits to harm others? Yes.
Is such behavior in line with the Theravada teachings? Absolutely not.
Theravada teaches any intent to harm is unwholesome.

I'm really uncomfortable with spirit-worship or anything resembling it. It gives me the heebie-geebities.
