>People die when they are killed
but if you break causality
>People can be killed without dying

The chain of causality goes like this
>the body cannot sustain life, so it must die
>the effect of the body being unable to sustain life is dying
>the effect of dying is death
but if you break the chain at #3
>the body cannot sustain life, so it must die
>the effect of the body being unable to sustain life is dying
>nothing happens as a result of dying
>the body cannot sustain life, so it must die
>the effect of the body being unable to sustain life is dying
>nothing happens as a result of dying
>the body cannot sustain life, so it must die
>the effect of the body being unable to sustain life is dying
>nothing happens as a result of dying
etc.

the subject is trapped in a cycle of infinite dying, but never reaches the state of being dead
