I think they can do good as well, but if we’re honest we know that what we think is good is much different than what they think is good sometimes. For example, an atheist would think it good to escort women to an abortion clinic for an abortion.
and a normal human would think it good to live by the golden rule, be kind to elderly and children, be a good steward to the earth, be kind to animals, help the needy, feed the hungry, clothe the naked, etc...the list goes on and on
