It was absolutely not out of concern for his own safety.
He was protected by Holy Light and possessed a transcendent body; ordinary illnesses could not come near him at all.

No matter what kind of experimental subjects they needed, or what terms they intended to discuss with them, there was only one major prerequisite.
They had to have experimental subjects first.
And they needed quite a few of them.
