> You can't build a functioning society or legal code based on "good and evil don't exist, we're all just animals" Of course you can. As long as the animals we are have the ability to understand the consequences of their actions, to themselves and others, and make rational choices about that. I wouldn't put in prison or on death row a person who killed even a hundred people but functionally has an IQ of 45. That person likely couldn't make rational choices and couldn't understand what they were doing, why they were doing it, or what would happen next. Whereas I would incarcerate a person with a 100 IQ who drove drunk in a well populated city, whether or not they hit someone. Good and evil don't have much to do with either case.
