In fact, he is the villain of the film. He is the one who pursues the group of teenagers, ultimately leading to their deaths.
The film focuses on the events leading up to the original *Texas Chainsaw Massacre*, with Hoyt playing a significant role in the terrorizing of the teenagers.
While the film doesn't explicitly show Hoyt's fate, it's heavily implied that he survives the events of the film and continues his reign of terror.
