If say you believe this dogma of eat the weaker then it is also perfectly fine for the person or mob, when resurrected and back in a position of power, to enact their revenge and take away skills, powers, or outright disown the said Orc for doing such a thing to begin with. This would be no different from squelching a perceived threat because you think they may jump you when you're at your weakest, so rather than fight, you simply end it before it begins. If I'm incorrect in saying such a thing then why would one of the adaptations be centered on sneaky, cowardly, dirty fighting?
