that's part of what i meant by consequences- this would come into play at some point. personally, i'd like to see what goes down.

Probably the reason why it's been bothering me is it

agreed. i just feel like a sequel would be warranted in this case to explore those consequences.

those ethics don't come into play until the source code world becomes 'real' though, in all fairness. there is no ethical dilemma in regard to the effects on that other world until it happens there.

all in all i agree with these dilemmas however that's precisely the foundation of a sequel imo.
