I think it's all one's choice on how they want to live their lives. Having or not having children is definitely not a trait of one's personality being better or worse!

I think some parents should have considered having children instead of having them just because (or by accident). And I don't think they're any better because they have children! Quite the opposite in fact!

Having a child is a very important step, and should be thought about very carefully. It's not a decision others can make for you. And I can't see what's wrong with not wanting them.
