Final answer:
The person's attitude towards Gregor transitions from sympathy to possessiveness and resentment as their initial pity turns to fear and repulsion when faced with Gregor's incurable condition.
Step-by-step explanation:
The passage describes a transition in the person's feelings towards Gregor from initial sympathy to eventual resentment and possessiveness. Initially, the person displays a sincere pity or concern for Gregor, which could be considered empathetic. However, as the situation becomes more desperate and Gregor's condition is seen as incurable, those feelings of pity transform into a sense of fear and repulsion. This shift suggests that while the person once held sympathy for Gregor, their inability to remedy the situation causes them to develop a more negative attitude, which includes elements of possessiveness and resentment towards him.
