I dont agree with that at all.
We may have free will, but that does not give us the right to behave like animals. And if we choose to do so, that does not make God responsible for it.
We alone are responsible for our behaviors. Blaming God for it is like blaming the gun for killing someone. We have chosen to bring evil upon ourselves by our actions, no one else. Adam and Eve had the ability to reject rebellion just as we today have the ability to reject it.
God made us. He made us with free will. He did so with the full knowledge-- being omniscient-- that we would abuse it by choosing to perpetrate evil on others.
That does not make God directly responsible for specific evil acts that human beings do. But it does make God ultimately responsible for enabling us to do evil.
To use your gun analogy-- which, to be fair, I am unsure is really a decent comparison-- yes, the direct responsibility for shooting someone belongs to the person who pulls the trigger. But if an adult gives a gun to an adolescent child, and says, "Now, don't shoot anyone with that!" and then leaves the child to their own devices, that adult bears some responsibility when the kid starts blowing people away.
No one is suggesting that because God, as the source of all things, also created evil, that makes doing evil okay, or that it absolves us of fault when we do evil actions.
But ultimately, we can say that God is omnibenevolent
or we can say that God is the source of all things. We can't say both.
I also think your implication about evil being the result of Adam and Eve ignores God's culpability for essentially doing the one thing any parent knows will backfire instantly: "OK, you can do whatever you want as long as you don't touch X. Everything else is okay. Just stay far away from X." We all know that's the surest way in the world to get a small child to do something as soon as they think you're not looking. And Adam and Eve were essentially children, in terms of their development. Their story is not about evil, it's a allegory for growing up and having to live in the real world.
I know Christians read it differently: I simply don't see that reading, nor do I have any reason to embrace it. But even in the Christian reading, God still either created the devil (or tolerated his existence and actions as a rebel, which amounts to the same thing), or one has to presume God not powerful enough to eliminate the devil. So God is still
either not omnipotent
or not the source of all things.
I think people hold this view because God has permitted evil. I just dont know where they get the idea that he causes it???
Personally, I think it is much more compelling to consider a God who is capable of evil but refuses to do so. That His teachings in fact represent advice to refrain from behavior analogous to acts of refraining that He Himself does.
Granted, it also raises questions about why He values free will enough to create us with it even knowing what we will do with it. But I would rather struggle with that question than either end up with multiple gods or a milquetoast God who loathes evil in all forms but is impotent against it.
