I've never thought of Nebuchadnezzar as a good ruler or bad.....All I ever looked at him about was that he screwed up and God taught him a lesson.
Jer 27 1 In the beginning of the reign of Jehoiakim the son of Josiah, king of Judah, this word came to Jeremiah from the Lord, saying, 2 “Thus says the Lord to me: ‘Make for yourselves bonds and yokes, and put them on your neck, 3 and send them to the king of Edom, the king of Moab, the king of the Ammonites, the king of Tyre, and the king of Sidon, by the hand of the messengers who come to Jerusalem to Zedekiah king of Judah. 4 And command them to say to their masters, “Thus says the Lord of hosts, the God of Israel—thus you shall say to your masters: 5 ‘I have made the earth, the man and the beast that are on the ground, by My great power and by My outstretched arm, and have given it to whom it seemed proper to Me. 6 And now I have given all these lands into the hand of Nebuchadnezzar the king of Babylon, My SERVANT; and the beasts of the field I have also given him to serve him. 7 So all nations shall serve him and his son and his son’s son, until the time of his land comes; and then many nations and great kings shall make him serve them. 8 And it shall be, that the nation and kingdom which will not serve Nebuchadnezzar the king of Babylon, and which will not put its neck under the yoke of the king of Babylon, that nation I will punish,’ says the Lord, ‘with the sword, the famine, and the pestilence, until I have consumed them by his hand. 9 Therefore do not listen to your prophets, your diviners, your [c]dreamers, your soothsayers, or your sorcerers, who speak to you, saying, “You shall not serve the king of Babylon.” 10 For they prophesy a lie to you, to remove you far from your land; and I will drive you out, and you will perish.
ALL of Daniel 4 and 5
And throughout mostly the minor prophets, there is stories of retribution against those who opposed Israel and lifted themselves high in their own eyes, and Israel did not do this, other nations were used to do it.
