Does that person not deserve pain? A mass murderer or school shooter causes irreversible harm on a massive scale, so the punishment should be as severe. They should not have the privilege to enjoy another day of their life, senseless murder or raping a child is the worst thing a human can do.
I go to a university that had a shooting in recent memory. The detrimental effect that event had on the students, families, and faculty should be addressed in a courtroom. In my opinion, the shooter should be sentenced to the same amount of pain and suffering as the entire school had that day. Imagine you send your child to uni and they are shot while enjoying their day, it's absolutely terrible and completely disgraceful. The shooter should pay forever, I think the death sentence is too easy.
And in terms of child abuse and SA, I can say from personal experience that it’s complicated. It’s most likely to be someone you know and are already close with, not just some random stranger. Harsher punishments make it more likely that perpetrators try to prevent any kind of reporting going so far as to kill the victim. Survivors often blame themselves for what happens after. Not saying that there isn’t more nuance to the psychological stuff that goes with that, but state violence doesn’t help
