If my first baby wasn't born by casesarean, both he and I may have died. I knew this from around 20 weeks. I suppose it depends on how you view things overall. For me, it was a lifesaver. There was no other option. When I was first told, I was upset but that was that, and I moved on. He is now 12 and I don't have the slightest disappointment that I didn't have him naturally.
I don't see the point in dwelling on something that, now, all these years later, isn't relevant (to me).
