The Japanese Shoguns built their entire warrior culture around masochism. Did you lose in battle? Congratulations, you must cut off your own head! Did you dishonor your general? Punishment consists of swirling your guts around with your own sword (yes, you're doing this yourself) and then chopping off your head. As you can see, failure - and disobedience - was not an option, and to commit it shamed you so much it would be more honorable to be dead than alive.
