Haha, if you can't recognize nuance or weigh different factors to come to a conclusion you are literally incapable of reason or logic.     If you are alive, you can enjoy a delicious slice of pizza. Therefore by your logic, I have found one reason  to exist, ergo the only possible conclusion is that you should have children.    In reality, the challenges or bad parts of life do not outweigh the good. Either way, you have provided no valid or reasonable arguments addressing that.
