Estimates are that 4% of the population is sociopath, no conscience, in it for their own gain.
These people gravitate to government for obvious reasons. Postion of power. Police, legislator, governor, lawyer, judge - all of these groups are probably more than 4% sociopath.
Sociopaths learn how to fake empathy. They are really good at it.
Agree.
Many anecdotes for many decades about what kind of people seek positions of social power (politicians, cops, lawyers, inspectors) or hero jobs (cops, firemen).
