Macbeth showed signs of confusion and some regret, or uncertainty about what he had done. He knew he was to blame for Banquo's death and was caught up in a mix of feelings. On the one hand, he felt good about fighting the one who prevented his rise, on the other hand he felt bad, because he knew he was a murderer, dishonest and he wasn't sure if he could show sadness at the funeral of the one who died at his hands. On the other hand, Lady Macbeth, showed no remorse for what had happened, on the contrary she was convinced that Banquo's death was necessary for her and her husband to have the power and influence they deserved. She knew she would be able to perform very well at the funeral and show sadness when she was happy about Banquo's death.
