Why would zaroff refer to shipwrecked sailors as specimens?

Zaroff refers to shipwrecked sailors as "specimens" to dehumanize them and emphasize his view of hunting as a sport rather than a moral issue. By labeling them as specimens, he reduces their value to mere objects for his entertainment, reflecting his twisted perspective on life and the thrill of the hunt. This choice of language underscores his sociopathic tendencies and the predatory nature of his character.
