Something for the players to beat to death? Plenty of robots for that.
Anyway, we know that at least some artificial beings have souls (androids). Therefore constructing one involves the manipulation of souls. Ergo, constructing a robot with partial AI may require the use of a partial soul.
Androids are made in ways that don't cross ethical and moral reasons, from what I remember the Android body is made and a soul decides to inhabit it, which is completely different than creating Undead.
That wasn't always the case. The first androids where originally constructed by humans as mechanical servants. Putting a soul into a non-living body is necromancy. Androids came into being via necromancy.
No it's not. It could be Conjuration since you're summoning the soul. We don't have exact rules for creating Androids so it's a moot point.
Androids =/= Undead
Android bodies where not alive before they gained a soul. Something that is not alive is, by definition, dead. Putting a soul into a dead body is, by definition, necromancy. This necromantic act may have occurred by accident, or at the volition of the soul itself, rather than have been done deliberately by the creator of the body, but it is still necromancy.
That logic is nonsense. Minerals aren't dead just for starters. No, just, no.
Er, yes, minerals are dead...
