Murder is such a tricky one too. It shares some similarities, with SA, CSA, domesticA, in that offenders tend to have extremely low recidivism rates or extremely high ones. Even moreso in homicide that crimes of passion, almost always husband/wife or girlfriend/boyfriend have among the lowest recidivism rates of any crime. However, when coupled with other prior criminal acts like SA, CSA or DA the rates of recidivism go much higher.
Which brings us round to predictive sentencing. The easiest low hanging fruit of how it can be both abused and cause major issues is drug 3 strikes sentencing guidelines. Then they tack seizures on top it can get way out of wack way too fast.
Then you cross it with the actual crime itself, murder. It is, in fact, the worst crime one can commit as it takes another's life. There is no amount of therapy, love or belief that can rectify murder as opposed to the rest. I am in no way diminishing damage from CSA, CP, DA, or SA as I myself know the pain and suffering from those, but... I did go on living.
My easy answer, is that I firmly believe repeat offenders of CSA, CP, or SA should face the very real possibility of life in prison. The worst counter to my own thought is the data shows the older one is the less likely they are to become recidivist despite priors. Fucking quandary. No simple answers which is itself frustrating.
