Does that mean that if Mahatma Gandhi, who preached non-violence (Ahimsa), could've killed just one man and still be considered good? After all he saved millions from oppression. — TheMadFool
Yes, Gandhi could have killed one man and still have been considered good. (Gandhi didn't personally save millions from oppression. He organized and led an independence movement in which millions of people participated.) Pick a great man or woman -- someone noted for their really fine accomplishments -- and somewhere in their history are actions that were not good. No matter who you pick, any real person for whom we have solid history, you will find a mix of actions over the course of a lifetime. Most of their actions will be of an indifferent nature; some will be exceptionally good, some will be quite bad. That will be true in your life, as well as mine. It's a universal feature of human existence.
There is a wide range of goodness and badness about any action that we judge, and there will be a range of goodness and badness in a whole life. Black and white all or nothing thinking leads us to very dubious conclusions. Take the situation where some people want to erase names because their whole lives were not 100% good. Take Woodrow Wilson and Princeton University. Wilson, born in 1858, was president of Princeton University starting in 1902, and had a distinguished career in public service.
Wilson is now accused of racist actions during his public life, actions which in the minds of some outweigh all the other accomplishments of the man, and they want his name removed from the Wilson School of Public and International Affairs. Thomas Jefferson is another case. Wilson and Jefferson are just two of many who are being judged anachronistically. By the standards of some 21st century activists, they were very bad. Wilson is accused of watching the film "Birth of a Nation" (1915) which is about the Ku Klux Klan while he was President of the United States. Well, of course -- the film was released while he happened to be President, and he -- and many other people -- arranged to see it.
Wilson didn't integrate the armed forces. Neither did Harding, Coolidge, Hoover, or Roosevelt. Harry Truman did, 30+ years and 4 administrations later. Wilson didn't act to open up Princeton to black students in 1902 - 1912. Neither did the president of any other Ivy League University.
Again, every life contains a mix of good and bad, and if we apply anachronistic standards, the record is even more mixed.
Some evil e.g. hate speech seem morally redeemable. — TheMadFool
You have named a very soft, squishy target in "hate speech". Such speech has been variously defined so that many statements which are quite neutral can be defined as hateful, if for no other reason that they do not fulfill the wishes of some group. For instance, taking the view that marriage is a heterosexual arrangement that doesn't properly apply to homosexuals can be considered homophobic hate speech. (I think it is legitimate for people to disagree about homosexual marriage.)
Others like murder are unforgivable. Some good like self-sacrifice are high up in the moral landscape while others like donating to charity aren't very laudable. — TheMadFool
Is murder unforgivable? And why is donating to charity not very laudable?
Pastor Dietrich Bonhoeffer, an anti-nazi Lutheran pastor, participated in the plot to murder Hitler. Is his action unforgivable? (as it happened, the plot failed -- the bomb injured but didn't kill Hitler.)
Is it that morality is comparative, or our judgement about morality is comparative?
Our general moral code says that murder is immoral. The law defines gradations of culpability, but law isn't morality. We judge actions by comparison, but our judgements aren't "morality"-- they are applications of morality.
Comparing Lee Harvey Oswald to Adolf Hitler, or Woodrow Wilson to Jefferson Davis, or John F. Kennedy to Richard Nixon are not morality, or moral actions, or moral judgements. What we do in making these comparisons is an act of historical judgement. Yes, I think Hitler was very much worse than Oswald, Davis was worse than Wilson, and Nixon was worse than Kennedy.
I'm not dismissing morality here, and it may play a role in our historical comparisons. But how does morality figure into a comparison of Ghengis Kahn and Caesar Augustus? Or Attila the Hun and Vlad the Impaler? Or St. Theresa and St. Catherine? Or Benjamin Disraeli and William Gladstone?
