That is a good one and one I own. It has a pacifistic (don't kill) sub thread in the plot but personally I thought it demonstrated clearly why only someone with superhuman ability can hope to stop evil in it's tracks without killing those commiting evil.
It's like Kenshin, who can get away with not killing because he's so good, it doesn't put the people he protects at risk.
There was a scene last night where all the townsfolk pulled out their guns at the robbers - I almost cheered.
