"Yes, of course it is, because creating the option to engage in evil is evil."
Your arguments do not hold water.
By the same token our constitution would be evil because it permits gun ownership, and guns can be used in a bad way. In fact, we can be certain that someone is going to misuse a gun in the next few days. So do you think allowing gun ownership is evil?
God has created beings with the ability to make choices. Many choices people make are against God's will. He does not instantly judge these sins because He is patient and merciful. But He has promised to judge the world in righteousness.
You have a very simplistic approach to theology, but at least you have given the subject some consideration. What you are not accounting for is the concept of redemption.
If we had the power to eliminate the evil that guns are supposed to countervail, then yes - so long as we did not also eliminate the evil that guns may enact, in which case it wouldn't matter if gun ownership persisted so long as the evil that they countervail were first eliminated.
God has created beings with the ability to make choices.
Then God's choice has consequences, and the consequences include the choices that would then be made by the created beings.

The approach is called "rational" - as opposed to these mental acrobatics trying to make the irrational appear to be rational.
