Were that the case as you state, then it denies Jehovah’s provision for repentance, awakening (and which will come for the majority I’m sure), forgiveness and justice. The scripture then must be weighed against those who knowingly pursue the evil course that you speak of. Paul is one such case that may illustrate the point in that murder was in his heart just as avidly as it appears to be in some in governance at watchtower. What has changed?
That such a reasoned state of (wrong) belief is possible in a clear mind and view of one’s faith, was shown when Jesus said at the last supper that “one of you here will betray me”. “It is not I is it?” Was the general response amongst them. Thus in the case of faith, it is not necessarily mental stability that informs the motive, but perception of self. If honest followers of truth can think that they are doing wrong simply by a single statement from Christ, then it requires self examination of a sound mind. And is that not what the lifting of the veil provides when it comes to it? Clarity. Certainty in understanding of the evidence of the course to take in repentance. One needs a sound mind for that.
Ignorance of the application of the word has never been a problem. Faith is an issue from the motivation of the heart. The bible tells us to pray for understanding, and to my knowledge, that has never been denied anyone. In fact, it is awoken in those whose minds are dulled in searching, but still yearn for clarity. Those whom are “satisfied” with having their ears tickled are left as examples to all when they are eventually awoken. Then, perhaps, at that time, the division between the apostles and Judas becomes clear, as was reflected when his position was filled later after he had judged himself. What he did, was done with clarity of mind, as will it be so for those decide for the beast.
If the mind of those seeking to deceive the sheep was ill beyond their capacity to reason, then where is the judgement? It stands to reason then until such time that people are free to examine the truth of the matter, that they should be entreated to think for themselves before hand “if they do not wish to share in her destruction.”
