Is incredible low Intelligence a sign my stalker has a brain injury?

I discussed that Yakov was a Hebrew time period for Jacob and inside 48 hours a man named Yakov messages me and asks me to show them about Christianity, I had been receiving loss of life threats by a mentally sick Jewish man for round 3 years at this level, would you say he suffered a mind harm if he’s that dangerous at making a plausible faux profile? I’m not saying Jewish persons are dangerous, I’ve met superb Jewish folks, however each backyard has bugs and this stalker of mine is an insect.
