So you pop out a fresh splicer ready for an ego to be sleeved. But isn't the splicer already a living human being before an ego is uploaded, doesn't it have its own ego? Sure its a blank slate but so was I when I was born. The morph is fully capable of learning and developing its own identity.
So aren't you technically killing the native ego of the morph?
If not sedated wouldn't a biomorph move and act like a newborn?
Or is there some "spark of life" that keeps biomorphs as empty meat-suits until an ego is uploaded?
