Was Eru a Sadist?

[HerenIstarion]

why isn't there any instances where Eru stepped in to pull out the source of his annoyance

If I were a parent, my will would be that my children behaved properly and tied up their room, but my will would also be that they were free. If I were to find the room in a mess, I would certainly have my will contradicted in one way, but carried along in another, since my children were free to mess it up. Furthermore it is question of my priorities, what is it I like best - tidy room or free children. (I would certainly prefer both at once, but if they refuse to clean up?...)

That's for it, and I would heartily remind participants it is not the place to vent one's spleen for the injustice (have you thought, by the way, whence such a concept as 'injustice' emerges?) of the universe, but the discussion board

thank you
