Rajaiya had been killing animals in the days before Sandaukan could kill him. After the young man killed a big fat wild hog, he could well wrestle him to death because it's justified that he's one of the Guillonks in all but legality, however not as physically powerful as Sandaukan would become. Bruises and blood are practically everywhere in the hero's last battle before being kidnapped off by pirates. Sandaukan wrestles the guy, bites off his neck, concusses his arms and legs, and bludgeons him in the mud without anyone even seeing.
