Yeah, I've always found these nihilists to be fairly shallow; they're stuck working from a bad perspective and can't allow for others. If you tell them that your life is mostly good and a net positive, they'll think you're lying or deceived.

I get that their life sucks; but my kids are happy, just like me, and a universe without them is a poorer place. Also, their existence allows for indefinitely more descendants, the overwhelming majority of which will be happy to be alive.

As a capper, I have four kids, so I've MORE than replaced myself.
