Possibly not, but there is nothing to suggest that these people are paedophiles. But they are abusers, and abusers have very high reoffending rates.
It may well be that neither of hear people will reoffend with pellet guns. I doubt though that their fundamental personalities will change and their desire to abuse and torture will continue.
We don't know if these particular abusers have personality disorders. But many do. It's true that not every narcissist or sociopath is a criminal - far from it, many are achievers - but once abuse has started I don't know how easy it is to redirect that tendency. Just because fists or sticks or pellet guns are no longer being used that doesn't mean the abuse has stopped. Narcissistic abuse is a thing in its own right with survivors often needing very specialised help, yet bringing the perpetrators to justice is often hard because they don't use physical violence.
