Alma 46:35

And it came to pass that whomsoever of the Amalickiahites that would not enter into a covenant to support the cause of freedom, that they might maintain a free government, he caused to be put to death; and there was but few which denied the covenant of freedom.

Any of the Amalickiahites who would not make a promise to support freedom and a free government were killed. Only a few people said no to the promise of freedom.

Any Amalickiahite who refused to make a covenant to support freedom and maintain free government, Moroni had executed. Only a few refused.
