Yes. I'm glad you grasp the concept of this factory. Look, it's either we kill this one creature every time we need rainbows, or we kill young pegasi. Which would you choose?
Well, look, would you either have one creature complain, who no one will miss, or have all the deaths of the pegasi on your conscience, and what their parents would think? (I can't believe I'm trying to moralize the rainbow factory.)
