总的来说，这是一种必要的邪恶。

It is by and large a necessary evil.

我认为相反也是一样：好人试图并努力去做每件事对战胜邪恶也是必要的。

I think the opposite is also true: all that is necessary for the triumph of evil is for good men to try and do everything.

如果阿纳金一开始除了邪恶就别无其他，那么前传根本没有存在的必要，因为已经没有故事可讲了。

Had Anakin been nothing but evil to begin with, then there's no need for the prequels at all because there would have been no story to tell.
