We all will die.  That is guaranteed.  

The 'death we deserve'?  Opinion only, and  subject to your personal biases, beliefs and prejudices.

A three-year old infant does not "deserve to die" or "die the death they deserve."  Nonetheless, three-year old infants still die.   

Shamans try to 'explain' such things by inventing 'theology' and 'doctrine' and other cant.  

Christian shamans, New Age shamans, Buddhist shamans, Islamic shamans.  Jewish shamans.  

Just ignorant people trying to justify their ignorance by inventing something to placate those who pay their bills.
