Is it selfish to choose not to have kids?

I grew up with a father who was present in the way furniture is present, and I spent my twenties in therapy unwinding what that did to me. Choosing not to have kids was the first decision I ever made entirely for someone else's benefit: the child who will never have to recover from my damage. People call that selfish because from the outside it looks like freedom, like I just wanted my sleep and my money. From the inside it felt like the hardest, most selfless thing I have ever done, admitting I couldn't guarantee I would be the parent a kid deserves. Not every childfree person has my story. But some of us aren't running from responsibility. We're refusing to pass the bill to an innocent third party.
