The man had the right idea as to what to do with radical leftists. And, when his work was done, he left on his own and restored democratic government.
Yes, too bad some here are ignorant of that.
Plus he left Chile a healthy capitalist economy. Neither all saint nor all sinner, Pinochet did handle the communists better than most and Chile is better off from his rule than it would have been from the same time under Allende, who planned to consolidate his marxist hold on the country and then to begin exporting it to the rest of South America.
