Is he not? If he had not tempted Adam and Eve into sinning, there would be no sin. Thus, no evil.
I'm not so sure of that.
What if Adam and Eve didn't eat from the tree, but one of their children did, as even though Eve was created good, she did not say the scripture right, though she was close, but as time would go by the story passed down, already Eve has it wrong and also added things, I would think that just due to passing it down, that the message would change, and eventually one of their descendants would eat of the tree of the knowledge of good and evil.
If Eve, the second human created got what God told Adam who must have told Eve wrong, then it's easy to see that had they not eaten the fruit that their children, grandchildren or any descendent could have, as the message would continue to be watered down.
Maybe not, maybe they would eat of the tree of life, but we don't know.
While scripture says God spoke about the trees to Adam, it is possible He spoke to both, but it's not written.
Now the LORD God had planted a garden in the east, in Eden; and there he put the man he had formed. 9 And the LORD God made all kinds of trees grow out of the ground—trees that were pleasing to the eye and good for food. In the middle of the garden were the tree of life and the tree of the knowledge of good and evil
.
And the LORD God commanded the man, "You are free to eat from any tree in the garden; 17 but you must not eat from the tree of the knowledge of good and evil, for when you eat of it you will surely
die."
The woman said to the serpent, "We may eat fruit from the trees in the garden, 3 but God did say, 'You must not eat fruit from the tree that is in the middle of the garden, and you must not touch it, or you will die.' "
I think since man had free will, that perhaps for example one man might accidently kill another, and what it the other got angry (normal God given human emotion) then killed the man.
Just to note,
anger is not a sin. God was angered many times in the OT, and Jesus (God) in turning over the tables, driving marketers out of the temple appears to be angry though it's not written.
But we also know from scripture that anger is not a sin.
If man had not fallen, they would be good, but given human emotions, I think it's possible that one would have sinned.
So, I'm not sure on what you are saying here is so.
However, I do not believe God ever wanted us to sin, but he gave us free will and knew we could sin.
