If a woman dies, we don't feel sorrow for any children (or their children, or their children's children, etc, etc) that will never be born. I am not a murderer for denying life to the billions and billions of people that will not be born if I've chosen not to have kids. Neither am I a hero for saving billions and billions of people if I choose to have kids (and good God, make sure my kids have kids and their kids have kids, etc, etc).
The question just comes down to: is it OK to keep animals to be farmed and eaten. If the answer is "no", then you gain nothing by bringing new lives into the world to subject them to it. If the answer is "yes", then there isn't a dilemma.
