From Unofficial Handbook of the Virtue Universe
Nihilist are people who believe that existence is without objective meaning, purpose, or intrinsic value. They assert that objective morality does not exist and that no action is preferable to any other in regard to it's moral value. In terms of religion, Nihilists believe that there exists no reasonable proof that a "higher being/creator" exists and if this(these) god(s) exists humanity has no obligation to worship.
In short, these people see no point for anything "in the end."
