Well, I have to admit that I don't see why not - Equivalent Exchange has been shown to have metaphysical as well as purely physical properties. The world has to remain in some sort of balance, otherwise alchemic rebounds wouldn't happen. Taking that into account, I don't see why balance wouldn't be a factor when it comes to whether redemption is a possibility or not.

Bear in mind that this has no relevance to me at all, as I personally don't believe myself to be redeemable, nor do I care to seek redemption in the first place. I'm just trying to understand your reasoning and frankly, I'm not following.
