Deciding to sell life to the Skull and Bones was a decision Chen Yu made after careful consideration.
Previously, Chen Yu was reluctant to engage in such dealings because he understood the lengths these powerful elites would go to once they discovered he could both extract life from others and extend it for them. Their desperation to prolong their existence could lead to actions that defied morality and ethics.
But after thinking it over, Chen Yu realized he was too narrow-minded.
Indeed, human greed and selfishness drive people to commit acts that violate moral principles and even the very boundaries of humanity, all for a few more years of life. But that premise only holds if they can obtain life through such means.
However, with Chen Yu controlling the source, ensuring these elites could only acquire life directly from him, as long as he himself refrained from unethical actions, there was no harm in it.
