can an Atheist have a concept of good and evil?

well now can an deeply religious man be moral?
let us start with Colin Myler - editor of numerous Newspapers, one in New York well US anyway)
Rupert Murdock was forced to sack him from editorships of Newscorps papers three times for publishing news and pictures that turned out to be scandalously false. The implication is knowingly false. Given the re-employment at the next newspaper. And what we observe of Bruno Merde's track record.

And this is a man who goes to church not just on Sundays but several times mid-week too.

Morals is for the common man. Amorality is not a word that has currency with the amoral. And the ME generation are in the ascendancy. Thinking of the neighbour is not in the cannon of the ME people.

Religion has the propensity to define and control morality, and the propensity for excess of it. But it is propensity as a statistical artefact. Not as absolute as its other dicta.
