Evil spirits can coax on accidents, even weird ones.
It is a reason to fear God, because if His call and capabilities and rights are not respected, He will at least temporarily leave us to our lonesome, and we fall to all manner of evil forces we would have otherwise been made to stand up to.
I won't go into details(this stuff is kept secret). But from my experience when there is a rash of suicides or heart attacks then a evil forces(black arts) are very possible. Direct experience for me, we were told to keep secret. These things are actually common in business and politics, both parties.
