You have misread Joseph Smith Jr's comments on judging righteously, which you certainly have not, are not, and will not do.
You are not Jesus, only a son of Lucifer Morningstar. Sit down and pay attention to your better angel.
Your first false premise........comparing Lucifer as the morning star of the Holy Scriptures. "I Jesus have sent Mine angel to testify to you these things in the churches. I am the root and offspring of David, and the BRIGHT AND MORNING STAR." -- Rev. 22:16
Or as Peter declared, ".......until the morning star rises in your heart...." . "And we have the prophetic word established, which you do well to heed as a light that shines in a dark place, UNTIL THE DAY DAWNS AND THE MORNING STAR RISES IN YOUR HEART." -- 2 Peter 1:19
Indeed, I allow the light from the Morning Star to rise and rest IN MY HEART......that morning star is Christ Jesus, and His kingdom resides only in one place..........within the heart of the Christian (Luke 17:20-37)
You are confusing the morning star mentioned in the Book of Isaiah......concluding that these passages about Lucifer were addressed to devil/satan, when in reality.........the subject matter is the King of Babylon who represents himself as a god among men. The morning star is a star that shines in the darkness and shines in the early morning dawn, in reality.........that star is not actually star, its the planet Venus. The symbolism in all the passages is that the light from this planet/star is always present to help defend against darkness.......and you should always allow it to reside or rise in your heart as it represents righteousness and good. In the Book of Isa., this king was actually representing/comparing himself to God.
Joseph Smith Jr.?

You mean the same Joseph Smith that plagiarized the King James translation of the Holy Scriptures......transmission errors and all and attempted to pass it off as New Revelations from Heaven?....that Joseph Smith Jr.? Or the Joseph Smith Jr., whose church authorized "polygamy" and racist bigotry by declaring that Black skinned people were black because of their sinful natures? That Joseph Smith Jr.?
I establish doctrine by actually reading the content of the Holy Scriptures. The scriptures declare, "Be imitations of me (the apostle Paul), just as I also am of Christ." -- 1 Cor. 11:1 If the Christ could not tolerate making a mockery by conducting business in a supposed house of God.......why should a modern Christian not be just as intolerant of making a business out of Christianity?...when the evil from man declares, "God loves you but send your money to my address............my jet needs repair.....or my dog houses need air conditioners installed....." Always preaching about how the supposed law of Prosperity........taking money from widows and people on fixed income by telling them....... will repay you 10 fold if you make a donation to MY SUPER CHURCH.
Judging righteously simply means to JUDGE in truth, not assumptions, speculations or conjecture. There is no doctrine against Judgment......men make judgements, decisions, every day of their lives. The scriptures declare, "For in the way you judge, you will be judged; and by your standard of measure, it will be measured to you." -- Matthew 7:2
"Do not judge according to appearance, but judge with righteous judgment." -- John 7:24
