Thanks for sharing this, that is an interesting data point.

A question that immediately pops to mind which cannot be answered with current information as I know it, is are these men who confessed representative of the majority of men who rape, or one subset? For example, in the study cited, while most rapes were done by repeat rapists, there were still many who did only do it once - this scenario seems most likely to me coming from that population.

On the other hand, I've been a domestic violence counselor, and I know "the cycle of violence," where an apologetic phase is part of a cycle that happens over and over. http://www.domesticviolence.org/cycle-of-violence/. From my training, we were told that men who do this almost never change, and that while they will go through this phase of remorse, that counseling almost never works to get them to stop cycling back to the behavior considered abusive. I don't know if any advancements have been made on that front since my training, which was several years ago. So anyway, if the cycle of violence which goes on in domestic violence between couples applies to the repeat rapists, then it would make sense that they would express remorse.
