I brought children into this dark world because it needed the light that only a child can bring.

The speaker frames parenthood as an act of moral hope rather than mere biology or personal fulfillment. “Dark world” suggests hardship—social injustice, suffering, or cynicism—while the “light” attributed to children evokes innocence, curiosity, and the capacity to renew adults’ sense of purpose. The line also implies a countercultural optimism: bringing children into a troubled world is justified because children themselves can be agents of emotional and ethical transformation. At the same time, it subtly shifts responsibility onto adults: if children bring light, parents and society must protect and cultivate it rather than extinguish it through neglect or despair.
