It might help also to note that if God were caught up in reacting to what evil does, this side of the end times, then God would no longer be God for He would be at the behest of whatever evil wants to drag Him into countering. Think about it ... God has a solution to all of this, but we neither see it as we go through it nor are we privy to the Greath White Throne vagaries to come and what exists after the great judgment.
True. God does not let evil go on without limit because as you say the tail would be wagging the dog.
