If you committed suicide your soul went to hell and you could not be buried in concentrated ground.
However if you were executed you got what you wanted (death) you could receive last rites, your soul would end up in heaven, (after the appropriate time in purgatory) and you could be buried in concentrated ground.
Interesting, and perhaps accurate, viewpoint. However, what if he had come to realize that he wanted to live, after all?
