I would interpret his response as “ I don’t have a favorite verse but I heard about this eye for an eye thing so I’ll use that”.
Based on his statements he doesn’t go to God for guidance or help. So he probably doesn’t put an importance on Gods Word.
He said. He loves God in that same interview, but that wasn’t reported. Nor did he say he never asked for forgiveness.
Hey, don’t be too hard on him. If he knew they were going to ask him about the Bible, he would have memorized a better verse, but that was the best he could do on short notice!
