Well,
For instance,
Churchill wanted to turn out British troops on the Jarrow Marchers,His own people,but he's regarded as "Great"
Very few "Greats" are unblemished
I didn't say Mandela was a Saint.But he was a Great man.
If someone had jailed me for 27 years I'd be looking for revenge.He didn't.
Compare him to the murderer Mugabe.
Anyway,no argument that "two wrongs " etc.
