I was not familiar with Honor Harrington until I just read her fictional biography. She sounds like quite an intriging character.
The side stories and politics are good too.
The People's Republic of Haven, the "star nation" Honor Harrington's people are at more or less constant war with, is real easy for a conservative/libertarian type to hate, a real distopic future vision of Marxism.
If more government is the answer, then it's a really stupid question.
I just thought of another favorite fictional character; Paul Atreides of Frank Herbert's Dune series. Paul is another character who went through immense changes throughout the stories. Paul is another "good guy" who does some really terrible things.
