I assume that you mean that God would want us to do something if we observed someone about to be fall victim (even if he/she doesn't realize that he/she is a victim) to someone attempting to delude that victim which was the question that you did not address directly.
You have me very confused now. You say that God sent his Son to rescue people from delusions and appear to agree that we should do likewise (I assume within our power) after commenting that "God does not send delusions, he merely allows it, because they prefer it that way" does not make sense to me.
How does Matthew 28:19-20 (a known later addition by the way which the NWT should delete if they are consistent) tie up with God doing nothing to stop sent delusions? I know that millions in thousands of sects are responding to this verse in word and more powerfully in deed - for some of them at any rate. There is no need for believers to feel too sad because the bible promises that all will be drawn to him. In any case why put people's salvation in jeopardy by telling them the message because the doctrine of most sects is that you can only loose salvation if you make the wrong choice after hearing the message.
