''There are passages in scripture that suggest such. I'm not stating it as fact.
You can put an argument to it being learning rather than concscience.''
You need to support what you say by quoting the parts that suggest conscience. It may be that there are other interpretations. You can see how many interpretations there on the identity and nature of these 'imprisoned spirits'
''The story says the "inclinations of the thoughts of their hearts" were evil from childhood. It says they were disobedient. They learnt how to be corrupt and violent the story tells. Adam and Eve hid in the bushes when they heard God. Cain asked if he was his brothers keeper and killed his brother. It suggests that kind of behaviour continued on. Evolution maybe. The flood rose when the soon to become imprisoned spirits weren't expecting it. They'd try to get away don't you think? It might act upon their conscience?''
The story tells us nothing about why people became inclined toward evil. Did God create them with a propensity toward evil, perhaps due to a lack of conscience? Why do people turn to evil? Are we that different? Were the conditions in which they lived conducive toward evil? Is God incapable of guidance? Perhaps does not care enough to intervene? Only complains when things go wrong, blaming His creatures, sending them to hell or 'imprisonment' for being what they were created to be: fallible. Finally intervening by drowning the whole world because He is dissatisfied?
