Final answer:
The creature experiences a turning point in his relationship with humans when he realizes that they are unfriendly and unwelcoming towards him. This insight is likely to change his perspective and behavior.
Step-by-step explanation:
The turning point in the creature's relationship with humans occurs in the passage when he experiences a moment of insight. This moment is when he realizes that the humans he encounters do not have a kindred feeling and are unfriendly towards him. He approaches them with a desire for connection and understanding, but is met with suspicion and hostility.
This insight is likely to change the creature's perspective and behavior. He may become more cautious and wary of humans, understanding that they are not as accepting as he initially believed. This realization may also cause him to become more self-reliant and independent, seeking companionship and acceptance elsewhere.
