Hmmm, only thing I don't like is that since this was done IC as an official set of regulations I didn't get to show much of the reasoning behind it.
So the basic philosophy behind this is as follow:
1.) KotMC is mainly concerned with punishing the evil, and in keeping with this it is only interested in slavery as a punishment, namely as a cheap, low-effort alternative to prisons. Any slaves that only need enlightening in the hands of a proper Holder need not, and will not, be kept.
2.) Knights are supposed to be warriors, not property owners or politicians, and taking slaves out of the control of individual members makes sure they can concentrate on fighting. This also means Holders who want to join have to make a moral sacrifice to be accepted. I consider it akin to a vow of poverty and humility, and without slaves a Holder cannot maintain much political power either. You give up wealth and power to make sure you are free to do the right thing.
3.) Sending out slaves as non-profit charity labor increases the Kighthood's standing with baseliner Holders and organizations.
4.) Corp-owned slaves means uniform standards for their treatment can be maintained. Nobody can whine about an individual member who is either too lenient or too harsh on his slaves.
5.) Any capsuleer slaves are beholden to the corp, not a particular member, preventing micro-loyalties from forming.
6.) This is a fairly neutral form of slavery. It's meant to be a middle-ground between many different ideas of the practice, including ideas from outside the Amarr-faithful nations, while still keeping in-line with new KotMC's strict moralistic bent. Only POW's and criminals are given the shackles, those freed are returned to their nations rather than becoming Amarr citizens, and this slavery is strictly for the benefit of the enslaved and society (all societies) rather than the personal profit of a Holder or the corp.
7.) By returning freed slaves to their nations of origin rather than making them Amarrian citizens, several things are accomplished. Firstly, it allows the freedom to release unenlightened individuals, rather than being stuck with troublemakers that will only screw up Amarrian society if they're let loose. This is ideal for POW's since they only need to be kept for as long as they are a threat to KotMC's interests. Secondly, anyone that does become enlightened will end up spreading the Amarr faith in their nations of origin. Instant missionaries! Thirdly, and this should be obvious, it makes the Knighthood look better to outsiders, while not pissing conservative Amarrians off too much. 'Look kids, grandpa is coming back since he's too old to fight and he doesn't need to be kept as a POW anymore! And don't worry Mr. Holder, he couldn't work anyway so it's no big loss. But he's still unenlightened heathen? Oh well, he was bound to die and burn in hell soon anyway so who cares.'
I'm trying to think of ways to make all of this reasoning clear IC besides having to talk to people personally... hm.
