why didnt he become a guard instead ?
just saw the last 3/4 of the movie ... from when he got to prison...so why didnt he just become a prison guard there and then kill the guy, instead of getting himself thrown in prison. then he had to escape (very dificult ) but if he was a guard he could have just shot him anytime he wanted and then just said "hey he took a swing at me or he was trying to escape" then after ya shoot him , just quit the job and go after the other guy ?
other than that it was a pretty good western
