What would your good do if evil didn't exist, and what would the earth look like if all the shadows disappeared?

You spoke your words as though you denied the very existence of the shadows or of evil. Think, now: where would your good be if there were no evil and what would the world look like without shadow?

But would you kindly ponder this question: What would your good do if
evil didn't exist, and what would the earth look like if all the shadows
disappeared? After all, shadows are cast by things and people. Here is the
shadow of my sword. But shadows also come from trees and living beings.
Do you want to strip the earth of all trees and living things just because
of your fantasy of enjoying naked light? You're stupid.

And now tell me, why is it that you use me words "good people" all the time? Do you call everyone that, or what?
- Everyone, - the prisoner replied. - There are no evil people in the world.

(- А теперь скажи мне, что это ты все время употребляешь слова добрые
люди"? Ты всех, что ли, так называешь?
- Всех, - ответил арестант, - злых людей нет на свете.)

Злых людей нет на свете, есть только люди несчастливые.

My writing is progressing slowly, but at least it's moving forward. I'm sure that's the case. The only problem is that I'm never absolutely certain that what I've written is any good.
