After the king is dead, Macbeth utters these words to show how deeply he is moved by his death. Macbeth shows how much he loved the king and how his life was just perfect when the king was alive.

This is classic equivocation, deceit to let thanes know that he had all the resources to kill Banquo but he didn’t as they both share common friends (enough reason
