I would, however, suggest that they are lacking somewhat in humanity. There is such a thing as being altruistic beyond the human norm, and this is an example of it.

Reminds me of one of the 101 Zen Stories http://www.101zenstories.com/index.php?story=13 :

"Hello, brother," Tanzan greeted him. "Won't you have a drink?"

"I never drink!" exclaimed Unsho solemnly.

"One who does not drink is not even human," said Tanzan.

"Do you mean to call me inhuman just because I do not indulge in intoxicating liquids!" exclaimed Unsho in anger. "Then if I am not human, what am I?"

"A Buddha," answered Tanzan.
