It's the only intelligent choice, although I wouldn't blame anybody who chooses to have children. Having children made me feel more empathy for others. Once you have experienced love for your own children, you feel more pity for those parents whose children live in pain, and for the children because you can feel their pain more intensely. Besides all the "small" human issues, such as mental issues as in this case, consider that human history is essentially a history of war and pain. I don't see any reason the future will be any different.

Oddly my comment is being downvoted. Most HNers act like a quasi religious group.
