Matter by Iain M. Banks

4.0

The implied threat of future cataclysms might be the result of coincidence, nothing more. 

Happily for the governing class, a well-formed faith also kept people from seeking their recompense in the here and now, through riot, insurrection or revolution.

A temple was worth a dozen barracks; a militia man carrying a gun could control a small unarmed crowd only for as long as he was present; however, a single priest could put a policeman inside the head of every one of their flock, for ever. 

tell him that it was all okay, that there was nothing really to worry about, that the universe was a terrible, utterly uncaring place and then people came along and added suffering and injustice to the mix as well and it was all so much worse than he could imagine

One of the last-resort methods of dealing with those displaying such voyeurism was to turn their own devices against them, scooping the surveillance machines up from wherever they had been scattered, fiddling with their software and then infesting the worlds of their creators with them, concentrating on the homes and favoured recreational facilities of the powerful. This usually did the trick.
