Unless they loved cruel sick jokes and hated My Little Pony. Shadow wouldn't fall under that category, though. But I do know some who would just kill her for fun and games in the most cruel ways.
in real life or the show and games the only one I can think of is mephilis I dont think eggmans that cruel because I have a theory he has a soft part for chaos and I think discord would want her alive to play games with her
