Well, we live in a modern world where abortion is nothing strange anymore. So it really is the motherīs choice to keep or not to keep the baby.

As for Itou and Sekai, sure both could be careful about that matter, but in the end, like you said, itīs the motherīs decision, so itīs also the to-be motherīs decision to be careful or not to be careful. If Itou isnt careful, oh well. If Sekai isnt careful, sheīll get pregnant. So one can argue as long as he wants, the main responsibility of pregnancy always lies on the womanīs side.

But now weīre off-topic, arent we? ^^
