YMMV / Firefly: Big Damn Hero

• Angst? What Angst?: Mal and Zoe are notably unperturbed about many of their fellow Browncoats dying at the end of the novel. Granted, Zoe has said she was ashamed of them, and they had just tried to hang Mal for extremely dubious reasons, but still, one might expect them to show a little more regret that their warnings about imminent explosive danger went unheeded due to an overabundance of gunfire.
• Complete Monster: Hunter Covington is a sadist to rival Adelai Niska. Working with a remnant faction of Browncoats to trap, try, and hang "traitors" to the Independent cause, Covington has no problem with the fact that these people are to be summarily executed by a Kangaroo Court, and stops by to watch Mal's planned execution because watching a man die by hoist hanging is his idea of a shiny evening's entertainment. He also keeps at least one bondswoman, who he plans to kill slowly by serious knife play for informing on him to the Feds. His neutrality during the war is explicitly because it was more profitable not to choose a side.
