"You take their lives with no compassion, as if killing a fly. They are Human Beings."
"They are cattle! and should be treated as such."
"But you were Human."
"Silence! I have lived 10 thousand years. Do you really believe I still carry compassion for these creatures? You will lose compassion very quickly, my boy. When you are sick of rodent and dog. When nights pass one after another and your hunger is all that guides you. When you grovel in the rain and mud waiting for a farmer to check his fields. When their blood is your survival. Talk to me of compassion after 100 kills."
"I don't know if I want this. Must I lose my soul to gain immortality?"
"Don't be silly, my boy...your soul is already lost."
