44 You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
John 8:44//

Satan was a murderer “from the beginning.” Interesting that a created being was sinful “from the beginning.”
