進むべきか戻るべきか to keep going or to come back

　道端になにかあると近寄ってみると、お気の毒、干からびたカエルでした。

　進むべきか戻るべきか。戻らなかったのが敗因でしたね。でも、戻れない事情でも何かあったのかなぁ。

　When I found something on the side of the road, I approached, and it was a poor, dry frog. Should he/she have moved forward or backward? It was its  fault that it didn't go back. However, maybe there was a reason why it couldn't come back.
