Sadly this discussion has veered in the wrong direction. Initially the topic was the origin of evil, more specifically evaluating the account provided by the Scriptures, and finding inconsistencies, lacunes, and so forth, yet many of the comments seem to focus on the human aspect as the source of evil. Were I to reply to KIDDO and BLUEWING's comments, this would take this discussion even further away from the intended path.
Therefore if anyone can...provide us please with a critique of the Bible account, namely 'how did Lucifer found evil'? Was there a flaw in the being Lucifer? One of the analogies we received here was with the way computers are build (see first & second page) namely that we're programmed, yet not to the extent where we're restricted to the fullest, an analogy which gives us an interesting perspective, yet I would like to further enquire and say, that that analogy still doesn't answer how did evil arrive in the picture, even if a being (divine or human) were to choose doing evil! In a loving, holy atmosphere such as heavens, (biblically speaking) how could evil even be a possible notion? If the account is not plausible, if the Christian Bible is mistaken in asserting and contradictory in affirming such an account, tell us why?
