Existence - not "better" than never existing

Coming into existence, or "getting to experience life", is not better than never 
existing.  It can't be, because no such comparison can be made.  Nor can 
existence be worse than never existing, for the same reason.

In order to say that anything is better or worse for an entity, one necessarily 
is talking about two different states of welfare or well-being for the entity. 
But an entity must exist in order to have a welfare state of well-being.  Thus, 
the comparison between existence and non-existence, from the perspective of the 
entity, cannot be made.  It is absurd.
