Why would a perfect being make an imperfect world?

[Socrates]

If you don't believe in a perfect god then this isn't aimed torwards you.

Why would a perfect being need/want to make an imperfect world with imperfect beings?

Well one, God created everything perfectly..

You have this individual who supposedly has no flaws at all, and he makes a flawed universe full of people who harm one another and who hate one another.

didn't start out that way. He simply allowed our natures to have a say

It doesn't make sense at all. Why would a perfect being make a imperfect world.

Again, he didn't.

If your first answer was free will then if Free will is such a limiting factor on making a perfect creation why have it in the first place?  It seems like that in itself is a mistake, intentionally making your creation with a huge limiting factor.

Free will does not enter the equation. Sin did. Sin being that which is not is God's expressed will for us. You may see this as imperfection, God sees it as being incomplete. So why does God allow us to be incomplete? To give those who want to be complete time they need to grow into God's expressed will for us.

But in a perfect world would a mistake be possible? You say the world was perfect but the beings that reside in it are imperfect. Wouldn't the beings be part of the world aswell and if they are imperfect the world they reside in can't be perfect either. Why would a perfect being put imperfect beings in a perfect world, he would know full well the imperfect beings would ruin the perfect world and it all falls apart from there.
