As it is you don't know the truth, at least not in its fullness, or else you'd recognize it in that post. You're locked into a handful of concepts developed by people strictly by reading a book, God's Word, centuries after the fact, divorced from its original historical context and recipients of its revelation, The concepts are plausible enough in some places, strained in others, often wooden and isolated interpretations in any case.
The alternative is that God is the author of sin.
"See, I set before you today life and prosperity, death and destruction. For I command you today to love the Lord your God, to walk in obedience to him, and to keep his commands, decrees and laws; then you will live and increase, and the Lord your God will bless you in the land you are entering to possess."
"This day I call the heavens and the earth as witnesses against you that I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live and that you may love the Lord your God, listen to his voice, and hold fast to him." Duet 30:15-16, 19-20
"Seek good, and not evil, that you may live" Amos 5:14
"Do not be overcome by evil, but overcome evil with good." Rom 12:21
"Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.” Matt 22:37-40
There's a reason why we pray, "Thy will be done on earth as it is in heaven". And that reason is because of the fact that His will is not at all necessarily done on earth as it is in heaven. God allows evil here, for a time, for a season, for His purpose, after which the two: good and evil, will be eternally separated, no longer allowed to co-exist as His plans for His creation are fully consummated. All truth and beauty and goodness in this world come from God while evil is done by man, coming from those who oppose Him and His will. So tell the victims of abuse, of rape, of torture, of genocide, of the holocaust about how beautiful this world is. You may get a different opinion.
Geez! It was nothing but love-speech, calling man to God and the love He's shown us. But man preferred darkness. What else is new???? Are you saying the darkness is somehow preferable or superior to the light just because man rejected the light?
