I think the insane sexual behaviour would most likely come from incel chuds failing time after time again getting a girl they deserve, resulting inSANELY masturbating to explicit material featuring anime characters in fetish-like situations and eventually, if there sexually fustrated enough, go on mass shootings at schools or around the city or hell, maybe at the park and kill themselves.
...and fat cobsons/rapesons that, again, masturbate to explicit material of anime characters in fetish situations, makes more sense now, doesn't it?
