If Genesis is correct about Eve and the apple, then didn't God make evil appear in the world on purpose?

Please, those of you who don’t believe can chime in but this isn’t about belief. Think about it as a story and you are trying to understand the moral or reason for a part in that story. So for argument sake lets say we are just discussing a story.
So in this story, God knows everything and created everyone. Even the Angel Lucifer who later becomes Satan. So he created Angels, I guess with their own will. He saw that didn’t work out so well and created man. Man was innocent. God told man and woman you can have anything but this Lucifer apple tree which is the tree of knowledge. Knowledge is evil so must be a Lucifer tree.
So my point is he shows this tree to man and woman who are as innocent and pure as a child and lets them be tempted? Why?
As a parent would you leave something deadly where your kids can get hurt or die? No. So of all the places this tree couldn’t be anywhere else in the world or even not exist at all.
Or maybe the truth is God let man decide if he wanted knowledge and that is what the real story is about and it started the ball rolling towards the deadly sins and maybe God didn’t see that coming.

So, back to my main question. Is God the true architect of evil, but not necessarily on purpose? Just left the choice to man to know more. I even laugh and thought maybe God got tired of answering Adams and Eves questions about why this or why that and thought the tree of knowledge would let them discover it themselves.
Just a theory I have because kids can ask all sorts of questions and the one nice thing about growing up is they learn to look discover things on their own.
