Tell it that struggling to stand and wipe one's ass isn't living because it's already dead due to limited movements. Its only alive watching its own existence literally be crushed by its own weight and laziness and will soon become a burden to the paramedics who will lift them to the ambulances and wheel them to the hospitals where it will be watching itself paralyzed alive as medical workers hook it up to various machines to keep it breathing. Oh and of course, dying from beetus isn't quick either. Its going to watch its feet rot off and if they aren't amputated, its legs will rot off as it nerves gets consumed by necrosis and diabetes in such painful ways that not even the most experienced surgeon could explain. Tell it that and hopefully, it may change even emotionally a bit.
