I never said it was morally wrong.
Just rather wrong in the sense that if you take a chainsaw to your arm, you will lose your arm. If your goal is to lose an arm, then by all means cut it off, but if you are not 100% sure that amputation is what you want, it may be wise to revoke the act before the consequences, which can not be revoked.
I am not altogether sure that the SET you speak of is the one I speak of, and my reference to HORUS, is only allegorical, that is whatever practice leads to the positive consequences of greater control over ones life I lump under the personification of Horus, those that detract from ones ability to take control over his life, I associate with SET.
As Gods are just symbols that represent nodes in our semantic web of constructed associations, not actual autonomous beings, There is no reason for be to assume your Set and my Horus are the same entity, as there is no entity.
Someone who is color blind has a different notion of gray than I do, and some of what he calls gray, over-laps with what I call blue.
Gray and Blue are matters of subjective category distinctions just as are Set and Horus. It seems to me that you take both Set and Horus to have light and dark aspects. Where as I take the light aspects of Set and Horus, and call them both HORUS. The Dark aspects of both I call SET.
(rather than light and dark, I prefer clarity/unity vs Confusion/dispersion.)
This is not unlike the notion in Discordianism that order can be creative or destructive, and so can disorder. Thus the Discordians prefer the Creative aspects of both order and disorder, where as most people seek order, even when it is destructive order they prefer it to constructive disorder.
But, ultimately we need to transcend these dualities, yet it is advantageous to create dualistic categories and linguistic labels for them in order to utilize them in the mind and the world (lower planes). However, it would be best if we see these as tools to get at truth rather than truth itself. I think we order the same dish on different menus, and argue about which menu calls it by its proper name.
Which tends to invoke a debate on Confucianism and whether or not names should be rectified, but that is for another thread.
