Yes, indeed they would be "judging" the word of God. But in order to judge we must have some criteria we're using to make judgments. A criminal judge is using the constitution and precedent from other court cases and internal morality. What criteria could we possibly appeal to in order to judge the words of God? What would have more authority than his words?
If you really think about that, you might find out the problem.
A judge would use quite a number of things. The constitution and precedent (tradition), morality, their own views (conscience)... all things human.
It is all we have. Even if there was something like "the words of God", we would still have to use all that tradition and conscience to figure it out. It isn't preprogrammed into us, it isn't obvious and crystal clear.
Human judgement, based on anything that you are able to base it on, is always your own. You alone can make it.
That makes it free. It also makes it fallible. This seems to be necessary... no one has ever found a way to align "free will" and "infallibility".
So if the creator intended his creatures to work in exactly this way, he cannot complain when they do work exactly in this way.
God did intend that his creatures would make judgements, but that they would judge all things in accordance with the words of God.
Then he should have made us in this way. He didn't, so you should consider that maybe he had a point in not doing it.
It would be incorrect to say that God is not interested in our opinions. God is not informed by our opinions nor is he swayed by our opinions.
Not being informed, not being swayed. In just what way is he "interested" then?
In the same reason that Shakespeare is not swayed by the opinions of MacBeth.
Not the same reason, not the same reason by far.
Shakespeare's MacBeth is not a conscious person. He is fiction. Fictional character do not think and don't judge.
They are rather "the same" as you think God's creatures should be. Fictional characters cannot do anything beyond what their creator has them do.
Humans do not work that way... and Christians state constantly that "God does not want robots". He does not want stage roles either.
By the evidence of what exists - us! - it seems he wants creatures who decide for themselves. If he didn't want to have them decide in a certain way, then he should have made sure they didn't. But he has only himself to blame for that.
