This is something that bothers me too, I was thinking about it just a couple of days ago funnily enough. If a soul is electromagnetic energy, and technology exists to capture one & force it into a body of the captor's choosing, then surely technology exists to disperse / wipe clean soul energy? Eenergy cannot be destroyed but it can be changed, eg. from intelligent/sentient energy into something else. Maybe heat energy to boil the kettle when they want a cup of tea.
