Goggles' existence had awakened him to the reality of the world. Even if you could manage to control things perfectly and bring back a soul just the same, it was impossible for you to curate and control every single one of their experiences.
Goggles had always been a person who fell in love with those he shouldn't and devoted his whole heart to them. He had done it with the wife of another man, and now Cynthia managed to take advantage of it.
The issue wasn't the flaw itself, but how it manifested. Goggles was almost practically the same person, and yet his experiences had caused him to go from the best of friends to the worst of enemies… and that was in the case that his soul actually survived.
