3 Fold Law, 10 Fold Law, Etc..., what you think about it? Options

I've read in many places (especially Wicca and Neo-Pagan related) that the 3-fold or 10-fold laws are very real. Yet again in other places I read that it was an invention in the 1970s and is only bogus to scare people.

But im always neutral in such matters so i've no say.

What do you think?

I could be wrong, and this may already of been said in a previous response but I'm in such a whirlwind of thought at the moment...
Anyways
I think the 3 fold law is simply a "myth" a superstition, I mean sure you cast a spell to make Tommy or Jane love you but there could be a consequence, that follows it. Theres a consequence with everything and karma follows every action performed. People should be prepared for the best and worst with a result. I'm still new to this, so I'm not quite sure.

I personaly dont belive in the threefold law. I belive it was made to frigtend pepole. I belive it is only real for those that belive it, or that have it in their paradigem so to speak. I also dont belive in an universal right or wrong. Right and Wrong, Good and Evil those consept wary from person to person.
