How does the creature show understanding and kindness to this family?

In observing the family, he discovers that they suffer from great poverty. The two young people are very generous with the old man, and often go hungry so that he might eat. The creature, greatly touched by this, ceases to take from their store of food, even though he is terribly hungry himself. He begins to cut their firewood for them, so that the young man, whose name is Felix, will no longer have to.
