Bodies, other than the sentimental aspects of it possibly belonging to a departed love one, are just more dead meat.
That can be a health hazard, and the bodies need to be buried or disposed of in a manner that removes that hazard.
During a possible crisis that resulted in thousands of dead bodies, the old "let the dead bury the dead" might have to be followed.
