Exactly- why the spheres were not made to be used with dead bodies, constructs, or something else I have no idea.
Because that's how the magic works. You're dealing with artifacts; who knows what limitations the creators were working with?
The point of the Taerans is that their existence DOES place them in a moral quandary. They are heroes - and yet, their continued existence is entirely dependent on the sacrifice of others. Place them in constructs, and they're simply powerful constructs - how is that interesting?
Looking to the Taerans, you have a number of factors.
- The orbs were not simply advisors: They were protectors and shapers of society. The magic of the immortal wizards and clerics held in the orbs would have been used for far more than battle; these epic-level spellcasters used their magic to advance their civilization and tend to the needs of the people.
- Between magic, knowledge, and discipline, the Taerans truly believed that their society was a utopia, whose people were educated and free of fear and poverty. The Taerans believed that they were helping others by bringing this civilization to them. Certainly it's not the first time that conquerors have thought that they were doing good by enforcing their values on others...
- The religion of the Taerans is specifically noted as being a harsh one - the Arbiter does what must be done for the greater good, and mortals must trust in his wisdom.
- In Kel Taera, the role of orb-bearer was a tremendous honor. An orb-bearer is a vessel through which society is preserved. As an orb-bearer, you have the chance to be Einstein or King Arthur - or at least to ensure that these noble souls live on to guide civilization. It was a noble sacrifice - and seen as a necessary one.
- The Taerans see the modern age as being hopelessly chaotic and primitive. It is a hell: if they can restore Kel Taera, they will make it a paradise. Yes, it is sad that a few souls must be destroyed in the process, and it is something the orbs will mourn and carry on their conscience - but they believe that they have the potential to bring order and peace to the world, and that it is their duty to do so.
The key point is that the lawful good Taeran is in all other ways a noble soul. He is driven by a desire to help others, to end suffering and fear and bring order to the world. He possesses immense powers that can be used to accomplish these goals. But to do this, he requires the sacrifice of a single individual. And again, in the past, the victims were all willing participants in this process. The Taerans have trouble understanding why a rational person wouldn't want to help them - the host has the chance to be the instrument of change, to bring a new golden age to the world!
Furthermore, nothing specifies that the Taerans
know that the souls are destroyed. The soul is eventually pushed from the body - but in Kel Taera, no one would ever have tried to remove an orb and recover the original soul. So it's quite possible that the Taerans themselves assume that the souls of their hosts are passing on to a well-deserved rest. Also bear in mind that the spiritual transformation is not an active process controlled by the orb. It simply happens as the orb-bearer gains levels; as long as the orb remains attached, it will overpower the soul of the bearer. Much of this depends on your use of the afterlife as an active part of your campaign. If the afterlife is something mysterious - as opposed to being a fun place planewalkers can drop by to have tea with the departed - then the destruction of souls becomes a hard thing to be certain of. Again, the only way to know for certain would be to kill the orbbearer, remove the orb, and try to restore the original soul - which the Taerans would never have attempted.
If the Taerans were evil, they would have no interest in ending the suffering of others, or bringing peace and prosperity to the world. They are not concerned with personal power or comfort. They do not enjoy dominating others: they truly believe that when others are shown the benefits of Taeran culture, they will embrace it.
My belief has always been that alignment covers a broad range of behavior. The evil man can be a ruthless murderer or simply selfish and greedy. The good person can be a kind social worker or a crusader who believes that destroying evil is the way to promote good. Like the Church of the Silver Flame in Eberron, the point of the Taerans is to say that people who truly seek to do good can still do evil, and can be just as dangerous or frightening as their evil counterparts.
Obviously you can make the Taerans evil or place them in constructs. But the point of the Taerans as they stand is that when they have the power, they will start striking out at the forces of evil - though they may be just as frightening themselves.
[Edit] Just to clarify another point: The orbs themselves do not actively choose to destroy the soul! The bearer chooses to implant the orb, and as long as the orb remains implanted, the transformation is automatic. The orbs are used to volunteers carrying the orbs, so again, it's not something they would think about: the bearer chose to make the sacrifice for society. So certainly, the creation of the orbs in the first place could be seen as evil - creating artifacts that would have to destroy souls to serve their intended function - but the paladin does not choose to destroy the soul of his bearer. Now, if the Taeran
paladin discovers that the soul is destroyed (like I said, I see no reason to assume he'd know) and that the victim is unwilling, perhaps, as a paladin, he would be driven to try to find a way to help the host remove the orb - possibly coming into conflict with Taerans of other classes who are more willing to accept the one act of evil in the name of good.
