If you're willing to broaden your definition of science fiction to include dystopian novels without a clear, overt treatment of science, you'd be able to find many more. Of course not all dystopian works count as sci-fi, but given that the former also typically deal with conceptions of morality and social order, it's not much of a stretch. Many of these works critique the notion that "the social" can only be adequately understood through a scientific approach. By extension, these works critique conceptions of civility as well.
Gravity's Rainbow, one of the most brilliant works of the 20th century, defies attempts to pin down its genre. It is realistic (in the sense of social/historical realism), profane in its surrealism, and deals with govt-sanctioned explorations of pre-cog states. This would be one recommendation. A second would be
Lord of the Flies, which is far less complicated than Gravity's Rainbow, but nonetheless features a critique of civility, barbarity, and morality given a dystopian setting.
