Unbeknownst to Jocelyne, Sobek hadn't limited himself to just hunting the boar.
He knew that the little girl was probably very hungry, but he couldn't worry exclusively about her. He was still a living being and therefore just like everyone he needed to eat a certain amount of food every day if he wanted to continue to live, an amount that surely wouldn't have been satisfied by such a small prey like a boar. Consequently, he had to hunt primarily for himself.
After all, humans, even though they had long since abandoned the natural state, had retained all the survival techniques they had evolved over millions of years: being able to survive for a long time without food was one of them. A human body could last for three months without eating. That little girl could therefore keep herself hungry for half a day. He didn't know how ethical this thought of his was, but in nature no one cared about ethics, so it certainly wasn't his problem.
