One never knows about situations.  Bizarre as it may seem. People may have all kinds of motivations perhaps not willing to entertain openly. Not in this case as it religiously motivated but heck money may motivate  in other such circumstances. For some it could be monetary. While alive welfare continues with cheques, pensions continue to come and who knows the status of the life insurance policy.  One never knows all the intricacies in such circumstances amongst humans. The yin and yang.

However, if  told to hire 24 hour care and take them home you would see how quickly the issue would be resolved.
