The inner sense of what is right and wrong is individualistic in nature. For example, recently buddhist monk self immolated, to his conscience and to many of those who believe in such measures, their conscience will not wrong such an action.

Whereas i do agree morality is complex, understanding it from a divine perspective makes more sense. Religion can at least help us explore it to a certain extent. In contrast, Atheism leaves no accountability.

The other issue is rising above humanity, the goodness of self sacrifice or mercy also do not make sense from an Atheist perspective. Religion can motivate such morality in a person.
