What about emotional pain, like the feeling of guilt? Like physical pain, it can warn us. We then listen to our trained conscience and avoid the wrong.
*** g02 3/8 p. 27 Feelings of Guilt—Are They Always Bad? ***
Feeling guilt can be good in at least three ways. First, it signals that we are aware of acceptable standards. It shows that we have a working conscience. (Romans 2:15) In fact, a book published by the American Psychiatric Association treats the absence of guilt feelings as societally threatening behavior. Those with defiled or deadened consciences have trouble seeing the difference between right and wrong, and that can be dangerous.—Titus 1:15, 16.
Second, a guilty conscience can help us avoid undesirable actions. Just as physical pain alerts us to a potential health problem, the emotional pain associated with guilt alerts us to a moral or spiritual problem that needs our attention. Once we are aware of the weakness, we are more inclined to avoid hurting ourselves, our loved ones, or others again in the future.—Matthew 7:12.

As perfect beings Satan, Adam and Eve did not listen to their conscience to stop themselves going down a dark path. They must have ignored the pain from their conscience stabbing them. So, I imagine guilt will also be a part of living acceptably in the new world. But not the awful guilt we feel now, such as when we might allow legitimate remorse over a mistake or wrong to intensify into feelings of shame and end up punishing ourselves unnecessarily. That negative feeling “will not be called to mind, nor will they come up into the heart“ - Is 65:17.
