I think that we all know what evil is. We have a sense of what's evil, and certainly killing innocent people is evil. We're less sure about what is good. There's sort of good, good enough, could be better - but absolute good is a little harder to define.
我认为我们都知道邪恶是什么. 我们有什么邪恶的感觉，杀死无辜的人当然是邪恶的. 我们不确定什么是好东西. 有一种好，足够好，可能会更好-但绝对好一点很难定义.
