I cannot for the life of me see why a supreme being would care about mere mortals following certain rituals, especially ones that limit the freedom of others and do not have a "net good" for the mortals, rather than the supreme being. That these rituals are intended as a test which emphasize suffering as being necessary on the part of the follower and often on non-believers does not strike me as being the mark of a being worth worshiping.

If a supreme being has the power to do good and prevent all evil (I can only believe in the existence of "evil" in regards the existence of supreme beings, even if religious people have done significant "bads" because of believing they have the ultimate truth), I can only consider that being to be evil. Doing something contrary to your judgement purely because of what such a being supposedly wishes should obviously be fundamentally wrong.
