I'm unaware of Cardith ever claiming to be a god, but he is described as a God-King in the pedia. I tend to think of his as an Enlightened despot who is in most circumstances an extremely tolerant ruler and would not start a religion to glorify himself. Of course, that doesn't necessarily mean he would be particularly eager to put down unofficial cults devoted to him. The Cult of the Dragon is quite popular in his lands, and is tolerated although it conflicts with the teachings of the Kuriotates' official state religion. Eurabatres might be walking a very fine line here to try to let his people's faith in him grant immunity to the influence of the evil gods while not taking any direct action to set himself up as a divinity lest he become as corrupt of the evil he seeks to destroy. Cardith could be an exception to the rule that worshiping oneself would count as worshiping Mammon, because he technically has 2 different selves that could worship and belong to each other.
