Agreed, except that I don't think Lucifer's situation was without explanation to some degree. God's creatures that are endowed with reasoning powers (mostly humans and angels) have creative capability and tendency and also an appreciation for beauty. Lucifer combined these two and created the sin of pride. In a manner of speaking, he lingered just a little too long in front of the mirror in preparation for an assembly. Thus he was overtaken with self-esteem and the notion that he could govern himself and others as well as God could. There's an entire video series on this subject here:Okay fair enough. Excuse suggests a lessening of culpability, and that wasn't my intent. I guess a better word would be explanation. They were deceived. The "traffic" and"merchandise" spoken of by Isaiah that was Lucifers modus operandi could be likened to politicking and/or slander. The lies of Lucifer must have touched on areas never before considered regarding God's character and His ability to rule in righteousness and justice. Lucifer managed to convince a large portion of the population that God wasn't fit to rule, thus sparkinga revolution and an attempt at change of government. So, while not excusable, I think explainable. But Lucifer himself, he has no excuse certainly, but neither is there any explanation for his rebellion. Thus why it's called the 'mystery of iniquity' I suppose.
