You know who was a good leader, according to Forbes "Leadership" columnist Sangeeth Varghese? Hitler. Showed a lot of gumption in WW1. And civil improvement? He was big on civil improvement. Of course, he had his drawbacks.
He always thought he was doing good. And sometimes he was. He oversaw one of the greatest expansions of industrial production and civil improvement Germany had ever experienced. His government sponsored architectural wonders, invested heavily in infrastructure and hosted the Olympic Games. Yet he emerged as probably the most evil man the world has ever seen.
See, a true leader doesn't just 'blindly follow down someone else's path" and massacre six million Jews; a true leader asks, "Does this massacre match my own objective sense of my principles?"
