I have a completely different opinion than the rest of these guys. You set certain parameters that he should have made some put in the time to practice. You feel he didn't do so and that's what you should base your decision on. I'd say no hunting this year.
It has nothing to do with how lucky he might get or anything else. It's the matter that he didn't learn the discipline to make an attempt. Rules are rules. You set them. It was his responsibility to adhere to them. To give in at this point might lead to him not respecting you later in life and this is what is wrong with younger generations today.
