Remorse: “I am sorry for what I did and the impact it had on the victim. I made stupid choices that hurt another person, and while I can never take that back, I will seek to do better so no one needs to suffer from my actions again.”
Not sorry you did it, just sorry you got caught: “I can’t reverse it, so I have to carry the consequences. It’s the biggest mistake of my life.”
Have you seen the panda that was raised by zookeepers? The zookeepers had to teach it to break bamboo, which was hard for them so they often grimaced while doing so. The panda learned to make a similar face, seeing it as part of the process. They’ve even caught the panda making the grimace after breaking the bamboo, like it realized that it forgot to do the thing and had to make up for skipping that step.
