Have Concern For Not Bringing The Nonexistent Into Existence So That They Don't Have To Have Concerns

I am more concerned about not bringing the nonexistent into existence than i am about existence because if no one is brought into existence, there will be nobody around to be concerned with existence. Or, more specifically, i think preventing the birth of sentient beings is more important than well-being because well-being is of no concern if there is no sentient life.
