If many people feel like the laws do not represent their morality, that's generally a problem, and will result in either change in the laws, or change in government altogether. They are quite intrinsically linked.
As for surveillance/war, although they have been supported by large chunks of the population in the past, I would say democracy aims to reflect the views of the majority. But it's also not magic, it's a fixed system -- a complicated system, but just a system. You vote for the person/party that best reflects your views. It seems quite a bit more likely to be a reflection of the people than other forms of government where the people tend to have less of a say, but not necessarily of course.
