...the bible actually indicated that God DID NOT want a monarchy.
That's not what the Bible says. See Daniel 2:21
He changes times and seasons; he removes kings and sets up kings; he gives wisdom to the wise and knowledge to those who have understanding;
Also, see Romans 13:1-9
Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore whoever resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of the one who is in authority? Then do what is good, and you will receive his approval, for he is God's servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God's wrath on the wrongdoer. Therefore one must be in subjection, not only to avoid God's wrath but also for the sake of conscience. ...
On the basis of these texts, I would say one who abolishes God's chosen representative has committed an act of blasphemy against the Lord himself.
