Knowing everything and allowing evil

[Some guy]

I lay a gun on a table and then put it on the safety catch, take out its ammunition, hide that in a box, lock the box, put the key in my house and then leave the gun (with my house locked too). Someone comes along and breaks into my house, breaks into locked box, takes ammunition, loads gun, takes off safety catch and kills a small child. How am I responsible?(not the killer the owner of the gun) I made reasonable precautions to stop the gun from being used yet someone was determined and still used it. Not my fault. Adam and Eve were commanded by God (the person they knew to be all powerful and stuff) to not eat of the tree, God did not place the tree next to where they were all the time but away from them. This shows the pair to have disobeyed God, taken conscious measures to get to the tree and then eaten of it. God did not create sin, all he did was create an opportunity that should not be used. I should not have to lock my door as in the Bible it says do not steal, but I do as people still steal. God did not have to give Adam and Eve massive knowledge for them to realise their they should not eat of the tree, so he did not and God did not have to chain the tree up and set up a guard post. The point of the recount of Adam and Eve is to show we always do the wrong thing, at least once, even if it it is simple. God did not create sin, he made an opportunity and if anyone made sin it would be the Diablo. Even if God knew that does not matter, he gives you free will and you choose whether he knew you were going to do something stupid or not. If God just sat around thinking "Oh if I create anything it will all do something stupid, so therefore I should not do anything" nothing would happen. God instead decides that it is not his fault we do stuff badly, it is the thing with the mind and in this case angles and humans. God did not create sin.
