Should I continue to let the ill, elderly guy bow hunt on my property?

I’m not talking about the morals of hunting.
I have an old apple orchard on my property that drops literally tons of apples during hunting season. That draws the deer in every night and since I am the only home in the area without a dog they hang around all year. It is a prime hunting location. For the past 20 or so years a guy has been bow hunting here without incident or any problems. He is the nephew of an elderly neighbor. He is unmarried, with very little money, and eats what he shoots. This is the highlight of his year.
A few years ago he was diagnosed with liver disease and was put on a waiting list for a transplant. I’ve watched him weaken and decay. He’s in his late 60’s but looks and moves like an 85 year old. He needs more and more help: moving the deer, gutting it, lifting into his car, taking his hunting clothes off. Two years ago he was unable to pull his bow so I gave him a crossbow which I cocked for him. I put a heater in his ground blind since he gets cold easily.
Here’s the issue: I don’t feel comfortable leaving him alone. He needs so much help – even if he does not get a deer. He can barely walk to his ground blind without being all out of breath.
I do not enjoy dragging and gutting a deer but I do it to help him out. (Ick.) The bigger issue is: I really don’t want the guy to die on my property. That would be even worse.

Should I say something or just grin and bear it knowing it gives him pleasure and food?
