Not all parents expect gratitude from their children for the mere fact that they were born. But I think you'll agree that such a pattern exists. And, like me, you've seen it countless times. And even more times it remains unnoticed, when a parent avoids loud arguments and drama, but secretly expects gratitude nevertheless, regardless of what kind of care the child received. I think it's very common, and I think it's very stupid.

Must everyone be grateful for the mere fact of their creation? What about Quasimodo? Or Corpus Colossus from Mad Max? People who were born with severe deformities, who live in constant pain, who cannot even take care of themselves. Must they be grateful?
Even the most average human-retard would concede at this point: demanding gratitude from such a person would be... wrong. But is there someone who holds the power to draw the line between "this creature must be grateful to its creators" and "this creature is free to curse them"? Aren't we all Quasimodos relative to what we may have been but never will be? So fragile, so weak, barely more conscious than the earthworms.

What about all those people who were born in perfect health but fell victim to circumstances beyond genetics and now live in perpetual suffering? Why must they be grateful to their creators?

If I were to create life, I'd have some expectations. It's pointless to do it otherwise. But I wouldn't be asinine or perverted enough to include unconditional gratitude to that list.

I am especially flabbergasted when human mothers weaponize pregnancy. "I carried you for nine long months and endured something you little twat can't even imagine! And this is what I get in return?! How dare you!" Just imagine how that would sound from the point of view of someone who's constantly in pain.

"Why would anyone ever think such a confession would make them look better and not A THOUSAND TIMES WORSE? Now I see. You were not like 'Yo guys, I have an idea. See this terrible horrible world? The one around us? Where everything wants you to be miserable or dead? How about I quickly create a vulnerable little girl here, just for shits and giggles? She will be so fucking abused here, and intimidated, and she will cry all day every day! It will be so funny! I mean, why not, right? It's not like this will cost me anything.'

"No, no, no, no. It wasn't like that at all. You were so evil, evil to the bone, and so deliberate in your wrongdoing that you decided to embark on a path to enduring a long period of suffering in order to bring even more suffering into this plane of existence. You went through hell... in order to bring hell upon others. You are The Devil!"

P.S. This may seem personal, but it's not. I'm simply an observer. My parents may have weaponized the fact that they "created" me at some point, but I don't remember such instances.

In fact, I am continuously grateful toward everything that allowed my existence. However, this feeling comes from spirituality, not rationality. But — what's probably more important — I am not constantly in pain. Quite the opposite, I rather enjoy myself. If it weren't the case, I may've had no trace of such spirituality.
