Whatever the real percentage of sociopaths and psychopaths, etc there are, we aren't going to be immune to. All we can do is be more sophisticated about power, money, representation, and keeping a really good eye on people.
But wherever that percentage lies, that's a lot of potential traitors. You have a Sangat of 100. What 3 to 10? More than enough in any group. And it's usually one of these that takes to politics, not always.
Fine line between crab mentality, and holding our representatives accountable or to a standard.
