No, that's not rational. Unrealistically high expectations are never rational. Nor is it rational to look at things, decide they aren't going the way to like, and decide you'd rather just not exist. A rational person looks at a problem and tries to find a solution. How is that irrational, actually? The first part might land you in jail, but since you think the world is awful and not worth living in anyway, jail can't be any worse. Not that I'm advocating it, but it's not entirely an irrational choice. And, as for the second part, that's exactly what most men set out to do (the women try to find as many great men as possible...and yeah, some exceptions on either side). The more you meet, the better your chances are of finding one who will reproduce with you.
The choices you're presenting aren't rational, they are rationalizing...attempting to justify an irrational act to yourself or others.
But, basically, you've failed to show any connection in your argument of why unfairness in the world should be a limitation for procreation.
Maybe you just don't like children and have no interest in reproducing and are attempting to explain that to yourself rather than just accepting that's who you are?
