Here's information from a magazine I get called 'The Week.' It seems a reliable publication.

'An adherent of the misogynistic "incel" culture last week shot dead five people, including a 3-year-old girl, and wounded two others before turning his gun on himself....Jake Davison, 22, killed his mother with a pump-action shotgun and then went on a rampage, blasting victims at random...

Davison had his gun license revoked in December following an alleged assault, but it was restored last month after he attended management classes.

He was a frequent visitor to internet sites where incels - men who are involuntarily celibate because they can't get dates - rail against women. Davison posted online that was a "fat ugly virgin" who was "defeated" by life. He signed off his final YouTube video by declaring, "I am a terminator."'

===========
The world saw this "incel" idea a few years ago where a man killed others in Canada. I think it was Quebec or Ontario - somewhere in the east of the country.

In this narrative I see a weak mind preyed upon by toxic individuals using the power of the internet.
