^Sorry, but that doesn't make sense. You're saying Satan has become delusional. If God is a forgiving, loving God, tinulungan na sana nya si Satan. Kaso, hindi e. Talagang hihintayin pa nya yung armageddon para makipag-battle.
I think same with some christians, they know the penalty of sins, they know God hates sin as it is written but would ignore, disobey or commit it anyway.
Do you know these qoutes?
"Some liars are so expert they deceive themselves."
"A lie told often enough becomes the truth."
"The man who lies to himself and listens to his own lie comes to such a pass that he cannot distinguish the truth within him."
John 8:44 says "You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and DOES NOT STAND IN THE TRUTH, because there is NO TRUTH IN HIM. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it."
And yes, Pride is a big factor also.
