neb: A standard trait for psychopathic personalities is "if I can't have her, nobody can". He can still cause an awful lot of damage if he decides to go down that route (but I think he's more a sociopath than a psychopath, so what we're seeing his him lashing out at anyone he deems disloyal rather than deliberate destruction).
If for no other reason than the following, I'd class Trump as a psychopath.
Sociopaths make up around 4% of the population, psychopaths 1%. Assuming the percentage holds true globally, that percentage translates to about 32,000 sociopaths worldwide, and 8,000 psychopaths.
I know the world's in a mess, but I think it'd be a damn site worse if there were 32,000 people as crazy as Trump.
BTW, many shrinks believe psychopathy is of genetic origin, with sociopathy due to childhood environmental issues. Trump's mental makeup may be a combination of both factors.
If world population is 7.8 billion then you're maths is way off.
It would be 78,000,000 psychopaths and 312,000,000 sociopaths.
