I do kinda understand why MC didnt want to destroy the camera, even tho its fucking him over right now, it did help him a lot before, and managed to get him together with the girl he loved, so theres tha. I would have destroyed it, but i can get why he didnt.
I think they main problem is with the store owner girl selling the camera to the first douchebag that presented himself, even when she KNOWS just how dangerous the camera can be.
