I don't really see a double standard - does the man not have choices over what happens in his body? Lets say two people light a fire together, then one of them leaves. It's possible for the person remaining to take action and put out the fire, but they don't, and it spreads. In that scenario, because the first person (who left) could have reasonably foreseen that the fire would spread, they are responsible as well as the second person (who stayed).
