Why did the creature stop taking food from the cottagers store?

The creature stopped taking food from the cottagers' store because he felt a deep sense of guilt and shame for stealing from them. He had come to appreciate their kindness and humanity, and he didn't want to harm them or take advantage of their resources. Additionally, he wished to observe them from a distance and understand their lives without intruding or causing them distress. This decision marked a turning point in his desire to connect with others while grappling with his own loneliness and isolation.
