Penny allowed Jody to go find the fawn and raise it because it seemed ungrateful tohim to leave the fawn to starve. He agreed with Jody that they had killed the doe for their purpose and the fawn was orphaned for no fault of its own. They could not let the fawn starve. They felt a responsibility towards it.
