Lucifer believed it is better to reign in Hell, than serve in Heaven. He was blinded by his own light. He didnt realize he was not the source of his radiance but a reflection of the light. Call it pride, arrogance whatever you like. He is the source of unrest. With pride our work is never finished. We always have to prove ourselves.
Satan [ Lucifer is a made up title Not found in Scripture ] could Never have said it is better to reign in hell because Satan was never in hell and never will be.
There is the teaching of a permanent un-biblical religious-myth hell theory, and then there is the Bible's teaching of a temporary hell or grave.
It was Jesus who went to hell the day Jesus died.
- see Acts 2 vs 27,31,32; Psalm 16 v 10
If biblical hell was a permanent place Jesus would still be in the Bible's hell.
Jesus taught [ Not pain ] but sleep in death [ R.I.P.] at John 11 vs 11-14
Jesus was Not teaching something new because the old Hebrew Scriptures also teach an unconscious sleep-like state at death such as at Ecclesiastes 9 v 5.
The Psalms also agree at Psalms 6 v 5; 13 v 3; 115 v 17; 146 v 4.
The Prophet Daniel also believed there is sleep in death at Daniel 12 vs 2,13
Satan will never reign in a 'hell' because Jesus will destroy Satan.- Hebrews 2 v 14 B
Satan ends up in a symbolic ' second death ' - Revelation 12 v 8 - which happens after everyone in the temporary Bible's hell [ grave ] is ' delivered up ' [ resurrected out of hell ]. See - Rev. 20 vs 13,14, - then emptied-out hell is cast vacant into that symbolic ' second death ' for vacated hell. Both hell and Satan are destroyed forever.
