He is a demon and does not understand the mortal world
He is a human being and should not step into the world of mortals
If the world has the best of both worlds,
If you don't live up to Tathagata, you won't live up to you.
He didn't understand until the end
"If we can take care of each other in the next life, I would rather betray the Tathagata than betray you."
