Our politicians exhibit all of them. The great Doug Casey writes:

The US is already in a truly major depression and on the edge of financial chaos and a currency meltdown. The sociopaths in government will react by redoubling the pace toward a police state domestically and starting a major war abroad. To me, this is completely predictable. It’s what sociopaths do.

There are seven characteristics I can think of that define a sociopath, although I’m sure the list could be extended.

1. Sociopaths completely lack a conscience or any capacity for real regret about hurting people. Although they pretend the opposite.
2. Sociopaths put their own desires and wants on a totally different level from those of other people. Their wants are incommensurate. They truly believe their ends justify their means. Although they pretend the opposite.
3. Sociopaths consider themselves superior to everyone else, because they aren’t burdened by the emotions and ethics others have – they’re above all that. They’re arrogant. Although they pretend the opposite.
4. Sociopaths never accept the slightest responsibility for anything that goes wrong, even though they’re responsible for almost everything that goes wrong. You’ll never hear a sincere apology from them.
5. Sociopaths have a lopsided notion of property rights. What’s theirs is theirs, and what’s yours is theirs too. They therefore defend currency inflation and taxation as good things.
6. Sociopaths usually pick the wrong target to attack. If they lose their wallet, they kick the dog. If 16 Saudis fly planes into buildings, they attack Afghanistan.
7. Sociopaths traffic in disturbing news, they love to pass on destructive rumors and they’ll falsify information to damage others.

 
The fact that they’re chronic, extremely convincing and even enthusiastic liars, who often believe their own lies, means they aren’t easy to spot, because normal people naturally assume another person is telling the truth. They rarely have handlebar mustaches or chortle like Snidely Whiplash. Instead, they cultivate a social veneer or a mask of sanity that diverts suspicion.
