So it turns out that Ichigo’s father was a member of the Shiba clan after all, which was apparently a popular fan theory, but I didn’t know that because I haven’t interacted with the fan community for some time. It was certainly my theory, put forward by me some years ago on a now defunct blog (convenient, isn’t it). I didn’t expect Ichigo to be part Quincy, though (side note–Zangetsu not being Zangetsu is dumb. I’m not going to go into it here, though). And about Uryu joining the Quincy–is he actually becoming evil, or is he just that dumb? I know he hates soul reapers, but think about it–he is actually destroying souls every time he kills a hollow.
The actions of the Soul Society are often morally dubious at best, but in this case (the destruction of souls by Quincies and the imbalance between the worlds that follows), it’s no wonder that the Soul Society issued a cease and desist to the Quincies, and took action when they didn’t comply. Was the situation so drastic that it warranted the entire destruction of the Quincies? I don’t know, since there is little background given–was it a war in which the Quincy were wiped out, or was it a covert operation of taking out the Quincies piecemeal? The author hasn’t told us, and the Soul Society would naturally write the history in a manner favorable to themselves. If the choice was really between destruction of one group (who would continue to cycle through reincarnation, because they were killed by Soul Reapers) and the possible destruction of these parallel or linked worlds (Earth, Soul Society, Hueco Mundo), then taking out the group, horrible as it is, is the more more utilitarian choice, no question. That is, if these worlds really work in the way which we have been told they do–perhaps it will be revealed to be otherwise, in which case I would a) be frustrated b) reevaluate the situation.
Finally, regarding the Vandenreich (a Quincy organization) and their motivations: what do they think will happen to the world if the afterlife is destroyed and they continue to destroy souls? Again, it is not only evil but deeply stupid. Then again, evil often is. So, while I don’t really like to take the side of the Soul Society, I feel that they are the saner and lesser of these particular two evils.
