In the assumption that you are real, because you think and therefor you must exist in some form, but have limited control of your perceived reality through your actions, you should make choices that maximize your satisfaction but your longterm satisfaction is actually dependent on not being an asshole.
Therefor, our lack of provable existence does not factor into whether you should or should not be an asshole.
But you’re not real!
