I'd just like to comment that, although you are quite right to say that compassion and service are not unknown in western religion, Buddhist practitioners take absolute responsibility for that and do not depend upon deities to imbue them with these qualities. One of the five daily recollections to be recited by Buddhist practitoners is:
I am the owner of my actions (kharma),
heir to my actions (karma),
born of my actions (karma),
related to my actions (karma),
abide supported by my actions (karma).
Whatever actions (karma) I shall do, whether good or evil, of that I shall be the heir.
