If the Chapter is so medicaly oriented, why don they use clones?
Many Chapters have tried using clones with little success. The Guardian Angels are not eager to follow in their footsteps. – They have full confidence that what humanity can present them with will be better, and believe that a clone merely represents the copy of a single entity, opening up for the possibility of a single error (like a virus) eradicating the entire Chapter. – Diversity is better!
