Rosh Hashanah 4: The Expected Corruption of a Non-Jewish King

On the corruption or lack thereof of Koresh (Cyrus). Is Koresh commissioning sacrifices and so on for his own selfish purposes? But isn't prayer often selfish in that same way? Or was he plotting to burn down the Second Temple as it was being built? Also, the prohibition against missing the timeliness of certain korbanot and other mitzvot. The 3 pilgrimage festivals have their own timeline to determine when vows kick in (eg, starting with Pesach and counting 3 festivals, or maybe just the one festival that follows that vow). Plus, the way Shavuot counts as 7 days for some issues, including avelut, even though it would appear otherwise.
