Yamaha don't have to expand into another industry. They make 180mph for-road-use motorcycles. They don't restrict them in Ireland to 70mph which is the speed limit here. This is probably because the world system is heavily based on the idea of free choice. There might be consequences for making the choices we make, but the world doesn't restrict us from making them. That is what it is to be human. To be permitted to make our own choices. The more you restrict peoples self-determination the less they can be human. The only way to prevent wrong choices is to give no choice at all. Had God done that he would have had created a bunch of automatons.
But you cannot relate in a reciprocally loving way with an automaton. On the other hand you can relate most fully with someone who has complete and utter choice in deciding to love back. For God to be able to express God-sized love he needs to create individuals who have free a choice. And it would seem to be necessary to provide something that is a complete 180 degree opposite to him. No shirking or loading the dice. And the opposite to him is pure evil. Man must be allowed to be able to choose pure evil. And he does...
This is not to say God made evil. He just made a system where evil could exist. Evil, like sin isn't an actual thing that needs creating. It is simply choosing opposite to that which God would have us do. All you need to allow evil to occur is to allow free choice
