The time had come to see whether his Carmine System lived up to his expectations.
His theories did not give Ves the certainty that pairing the Dawn Star Project with his grandfather would save the latter's life.
He truly did not know what would result from this experimental outcome.
Such a procedure would never be able to pass the review of any proper scientific panel. Ves not only broke enough ethical boundaries to turn him into a pariah, but also rushed this project so that he could get everything done in little over a week!
It was not as if Ves didn't want to do better.
He would have preferred to take his time and conduct proper studies on his Carmine System. He should have completed his Blood Knight Project a long time ago and tested the effects of the Blood Pact on many different pilots to confirm that it was safe and that it operated within parameters.
