Ferdinand refused to negotiate with rebel vassals after 1492.

Evidence

The outcome, however, was very different. In the fighting leading up to 1492, Ferdinand, through Zafra, had usually been willing to strike some deal because it served the overall Castilian policy to do so. That was no longer the case. Ferdinand held that he was not dealing with legitimate enemies but rebellious vassals who had forfeited all claims to consideration. (He had adopted the position put forward by Cisneros.) Those prisoners who had been spared the fate of being cast down from the tower were reduced to slavery and sold, as were the womenfolk and the children. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 238

• ADDENDUM: The refusal to treat surrendered rebels as legitimate enemies who could win terms, versus as rebellious vassals with forfeited claims, parallels the sacrifice chapter’s treatment of how political actors frame violent submission — here the absence of negotiation itself becomes a mechanism of terror.
