Basically the luck of being crewmate and imposter

when you get voted out when you're imposter; when you get voted out when you're crewmate; when you get killed when you're crewmate but the crewmates still win; when you get to be crewmate and you live for the whole game; when you get to be imposter and you win when you faked tasks; when you get to be imposter and you win when you didn't fake tasks; when you kill a crewmate when 10 other crewmates were around that clearly saw you kill that crewmate but still don't vote you out
