We have free will, despite all the baggage of our upbringing, education, etc. One may choose to be compassionate and helpful, and cite religious reasons for doing so; one may be cruel and cite religious justification. One may be compassionate and helpful and cite secular philosophy to explain his or her actions; one may be cruel and justify one's actions as naturalistic, darwinistic in nature. Either way, one's beliefs are subjective. We can't know either way, so we choose based upon who we are and who we would like to be.
