A Cultist Is Threatening To Kill Him, He Needs Your Advice

There is this guy who lives on my street. He is a cult member and everybody in the neighborhood knows.

I have always kept him at arms length for years until recently that i let my guards down.
All of a sudden he starts threatening to kill me and the last time will make it the third time he will make this assertion.
I have done nothing to warrant such and i believe he is only trying to intimidate me into submission since he always asks for hand out and other favors which i often decline.

Could someone please advice on the best line of action because he might be meaning to do what he has threatened to do.

Mods should please take this to the front page for proper advice..

Thanks.
