No. As Sideshowbob tries to point out, Lucifer's sin is not ignorance, but pride. Ditto Hitler, and Trump. One can take pride in one's own ignorance, too. I know that I do. Pride is a violation of the first commandment, and the mistake most infamously immoral folks always seem to violate on the way to much more serious moral transgressions against more people.
Lucifer is the bringer of light. Shining a light on the truth is the opposite of ignorance.
The "fall from grace" is an understanding of the difference between good and evil, a loss of innocence but also a loss of ignorance.
Nice one, SSB. Truth is only a value, not an absolute. If you don't value knowledge about something, that's ignoring it, and that's always a value judgement.
We choose not to ignore those bits of knowledge we deem vital to our survival and ignore millions of other bits because they aren't, because that's our highest value. A ripe tasty apple low to the ground is hanging where you can easily pick and eat it, but a hungry tiger is crouched nearby, waiting for you do that because its survival also depends on whatever happens next. Which do truth do you choose to ignore in that situation; the truth about the tasty apple or the hungry tiger?
Ignorance is a vital part of knowledge that works to keep you alive. What you choose to ignore in this election is similar in some ways. Someone chose G.W. Bush to be president and look what happened. Those were our children shipped out to Iraq and Afghanistan, and the fallout from that masterstroke is still on the front page. What administration finally captured Bin Laden?
Talk about modern belief in nonsense. Like the Saudi's had the best interests of the American people at heart. We'll run out of children before they run out of oil. Believe that.
