I'm not familiar with this phrase, but maybe if you could give us a bit more to go on. In what sort of context in the movie did you hear this said? Did you hear it only once, or is it repeated often? Where did you get the idea that it meant "to live to die"? (from subtitles?) And do you think this means "to live with no purpose other than dying", or am I reading the English wrong?
In a martial arts context, "teki" will often refer to "the enemy" or opponent, so that doesn't seem to quite fit your understood meaning. "Sho" (if it's a long o, i.e. "shou") could be "life". I'm just grasping here
