It gives me joy to consider his mummified body in a glass case for people to look at. So, from a utilitarian perspective, of the greatest happiness of the greatest number, we would have to compare and count the feelings of people whose opinions are more like yours, and people whose opinions are more like mine, and also factor in the other consequences of the creation of his mummy and display of it, to determine if it fits or does not fit with utilitarianism. It is far from obvious that a proper analysis of all of that would turn out as you predict.
