There is obviously a common denominator to a sexually frustrated incel mass killer and a sexually frustrated serial killer, and I wonder how many of the incel mass killers are just "retrained" serial killers in the current socio-economic reality. In a way, this would mean that they have "adapted" to the changing social reality, lol.

Anyway, the root of the problem is in a sexual frustration, and it would be funny af if the modern surveillance state created a mass killer out of the traditional serial killer.
