I always find these threads curious. What purpose would a longer sentence serve? It won't bring her back. Prison shouldn't be about punishment, it should be for rehab.
I wonder what would happen if locking someone up wasn't the only option we had... What if:
1. If we had the technology to change a person to remove the ability to perform the act that was in violation of the law. A sort of mental castration that would remove one's ability to murder, rape, steal, etc. Would you guys be OK with forcing the procedure and removing a bit of free will with no jail time attached?
2. If we had the technology to alter a criminals state of mind so that the criminals perception of time is dialated, say to a maximum sentence of say 1000 years subjective time. And let's say that was actually an hour or so in real time. Would you be OK with that sort of sentence.
3. If we created a global and benign AI and gave it the ability to surveil us all at times and intervene just before the moment we break the law of our society, would you be OK with that?
4. If we discovered a way to predict people with an 85% chance of committing a felony of any sort, but not 100% and no idea when it would happen, would you be OK with preemptively removing them from the gene pool before they can do harm. If you do not approve of killing them for something they may or may not do, let's say he has Matrix-like technology. Would you be OK with imprisoning them I'm a VR simulation without their knowledge and letting them live subjectively free, but cordoned off from the real world for their whole lives?
