While the Bible does not specifically say what happened to the souls of the Nephilim when they were killed, it is unlikely that God would destroy the Nephilim in the Flood only to allow their souls to cause even greater evil as the demons.
Wakati Biblia haisemi hasa ni nini kilichotokea kwa nafsi za Nefili wakati wao waliuawa, kuna uwezekano kwamba Mungu bila kuharibu Nefilimu katika mafuriko na kuruhusu roho zao kusababisha mabaya hata zaidi kama mapepo.
