Genesis:
15 Jehovah God took the man and settled him in the garden of Eʹden to cultivate it and to take care of it.n 16 Jehovah God also gave this command to the man: “From every tree of the garden you may eat to satisfaction.o 17 But as for the tree of the knowledge of good and bad, you must not eat from it, for in the day you eat from it you will certainly die.”
The teachings tell us that Adam and Eve eating from the tree of knowledge is what unleashed evil all over the world.
Evil such as war, child sexual abuse, genocide, and all kinds of horrors.
But if God made the tree, then he created the bad that went into it as well, no?
