Islam and Christianity. (Not the answer you wanted was it?) If you want to
be part of a successful and effective stategy for the long term survival,

Ethics is not about what works best, that's simple Utilitarianism. Ethics
concerns itself whith what actions are good or right or proper, even in the
face of seemingly limited utility or effect.
