Might also be useful to remember that "alive" or "dead" qualities are not value judgements (i.e. alive=good, dead=bad). They are different techniques.
Alive hand is preparation for continuity of the fight. My Hop Ga teacher taught dead hand as the ideal method for the most telling blows. The arm is used as a flail with natural rebound from the target once the energy is gone. There is no attempt to modify the momentum once the target is attained. Often the preceeding or following hand will be more alive.
You might think of live hand as an epee, dead hand as a war hammer.
