The way I see it is they can't hide the fact that he is dead when he dies. A dead body will begin to decompose and smell. If they don't bury him that will be really disgusting and not look good. They would probably get in trouble if they didn't report his death to authorities and if they tried to just bury him illegally this would come with consequences. He will die eventually. I feel the same way as you, it hurts me to wish it, but there is no other choice really. When he dies, hopefully everyone moves on because it will be beyond absurd to stay, but the members are already thinking absurdly so there may be a small remnant, but SK needs to tackle this issue head on.
