If Hitchen's challenge is correct, then why are there ethical lapses?

Note he says "moral or ethical action or behaviour". Not to any particular standard of morality. (Note since the Bible is also morally ambiguous and/or impossible to follow literally, that's true for believers as well.)

People never believe they are evil. They can justify what they are doing as right; it's practically why our brains exist. His argument is that belief or non-belief doesn't affect our possible range of choices.

How does one determine what "moral or ethical action or behavior" is, unless it measure up to a certain standard of morality?  And what you said is a kicker here.  Anyone could take what Hitchens said, and if they don't want to do anything, don't label the issue in questio as an ethical necessity.

"moral or ethical action or behavior" = choice. that we make. good or bad by anyone's standards. I'd like to see the context - does Hitchens mean for that statement to mean 'good'? Right now it reads like 'any'.
