Anything that involves working with powerless people, whether it's children/teenagers, sick people or the elderly, will attract perverts and serial killers. So schools/medical institutions/law enforcement etc are prime real estate. Any domain that promises wealth, fame, or power will attract sociopaths and narcissists. This includes finance, entertainment, and indeed the tech industry.
