If you had a chance to "do unto others as they have done unto you" would you?

Here are a few details they (adults) in their 50's have terrorized my six year old son. Falsely called child protective services, which nothing was found wrong. In fact we were told that if they called again it would be considered harassment and they would file charges against the ones who made the call. Calling the police on my husband filing false battery charges. Which were later dropped. Threats of "we will make your life a living hell everyday until you move from (the state we live in)". If my husband's grandmother passes they will have an autopsy done to prove we killed her. I mean these people are CRAZY. They have ruined our good name and standing within the community. They have been in this community for a great deal of their lives so they have already established themselves and pose as God fearing Catholics.
