A second reply. If you sincerely believe all behavior is based on self preservation, perhaps you do not understand that a sincere Christian, seeing each person as good and capable of more good and worth suffering for, can thrive in all sorts of environments, being a angel to others and not being untrue to God and without being a notable asshole. We have songs for training people in how to do this, about Love and the Christ in me greets the Christ in thee and on on.
