Can terrorists and criminals be a government, or even a democracy? Or when they constitute a government do they hold some sort of mandate? This is a ethical/moral philosophical question having to do with natural rights. What exactly is it that gives someone the right to trespass onto the natural rights of others (as a government is entitled to do)? This is a very central question in political theory, or as far as normative political theory goes (i.e. what should be). In the Judeo-Christian perspective, the fact that someone was a king was a manifest sign that they had been appointed by God, in some sense, to be king, even if their rule was not altogether righteous and they did evil (which was frequently the case). The people had a duty, both temporal and moral, to be obedient to the king (with some exceptions when it involved something personally immoral or was incompatible with their duty to God). Obviously someone could not remain king if God did not allow it.
