My argument so far, is that one needs morals to live in a society, because morals regulate ones relations with other people. We all ultimately tend to rely on other people for our health and (to a greater extent) our sanity. If you had everyone killed who didnt agree with you (although one's sanity would already be open to questioning) then you would be regulating a society by your morals (this doesnt mean right or wrong in general, just right or wrong in the context that had been created.)

If I understand what you are talking about in post no. 95 (and I dont know if I do), then it starts off with dissenters lying to themselves, but eventually everyone becomes indoctrinated with the ideas coming from the goverment. For ways that this happens, read some stuff about the cultural revoution.
