Road-Crossing Analogy

When consent is properly understood, it applies not only to the action itself but also to the foreseeable effects that flow from that action—even when those effects are unwanted. Crossing a road does not mean someone wants to be hit by a car, but it does mean they accepted a set of known risks tied to the act of crossing. Likewise, sex is an action with a well-known biological function: it can result in the creation of a new, inherently dependent human being.

When that foreseeable outcome occurs, the moral question is no longer about whether the outcome was desired, but about how one may respond to it. People are generally permitted to mitigate the negative or difficult effects of their choices. However, there is a clear moral boundary: mitigation does not justify committing a wrongful act. Treating an illness caused by lifestyle choices is morally acceptable precisely because the treatment does not require killing another person. If curing the condition required intentionally ending someone else’s life, that “treatment” would be ruled out as impermissible.

Applied to pregnancy, abortion does not merely manage an unwanted condition—it intentionally kills the very human being who exists as a direct and foreseeable result of the chosen action. The minimal obligation that follows from creating a vulnerable human is not heroic self-sacrifice, but simply refraining from killing the human who was placed in that dependent position. In this way, abortion crosses the same moral line that would be crossed if any other foreseeable consequence were addressed through lethal harm to an innocent party.
