Believe In One God Or Die?
When one sees death in front of him, the time for repentance is over. Similarly, when Allah has announce the death for His criminals, their time to revert or repent should have been over. Giving an option to believe or die looks like making them say yes on a gun point. I have no problem with the Ittamam e hujjat principle — so the links you have shared don’t seem to be relevant.
