I wonder how easy it's to hire guys for a job with the introduction: "There's a bunch of possibly insanely strong people with strange abilities you wouldn't be able to understand in a room and we want you to rush in armed with obsolete weapons to try to kill them. These people were chosen based on the expectation normal humans, such as you guys, wouldn't stand a chance against them, but we just have to make sure. So, do your best, even though if everything goes well, you'll all be corpses."

Kurapika's hatred gives his character a nice, focused vibe, even though it also tends to make him lose his cool.
