We alway cut great minds a lot of slack. I have a mental experiment for this: imagine a man beats his wife. Terrible right? Now imagine the same man cures cancer. Well suddenly everyone is curious about the complexities of his marriage. That’s morality for most people.
It's interest balancing. If you do a lot of good, more evil is excusable in the mind of the average person. It doesn't make the bad things less bad, but it makes the person more human, as opposed to them being a virtuous angel, which nobody likes.
