You haven't done anything of the sort. The only reason why I'm still here is for others. Are you telling me that the only reason why children exist is for the benefit of others? That's really fucking disturbing.
You're mad because you know that I'm right. You're mad because you know that the creation of children cannot be justified in this day and age. You're mad because somewhere inside your skull, you've come to the realization that (if you've created children) you've brought them into what is very likely a doomed world in which they will eventually experience a hell like nothing any other human had ever experienced.
Good job, you selfish asshole. Your children may one day grow to be miserable and ask you why you had to bring them into the world. Then you will have to face them, look them in the eye, and tell them that it was all about your own happiness, not theirs.
