Other than 'footpath' there is no word with 'path' in it that I understand. In an English court we would render the highlighted text from Massei by saying they were young people of previous good character, especially no history of violence, who acted without premeditation. Does Mach disagree with that?
If I agree or disagree, this would depend on the meaning your are giving to the words "good charachter".
In other words, from my point of view there is just a caveat, and that is about the meaning and implication of such concept "good charachter"; it looks like Bill likes to extend, widen or inflate and universalize right this concept of "good charachter", he starts to build pictures and draw inference along with his own imagination, what he thinks "good charachter" is, goes further thinking that it is the equivalent of saying that they are two "normal kids", that is psychologically sane and normal, with "no psychopatology".
My caveat, instead, is about pointing out the very limited scope of Massei's statement. Massei is making a reasoning strictly limited within a narrow scope of topics, that is a reasoning limited to what pertains to the defendants being entitled to obtain generic mitigation.
By the way (it is a non connected topic, but just to give you an idea) you may recall that, under Italian law, even the 60y old man who had sex with the 11yo girl was entitled to generic mitigation, because the man had a caring attitude and the girl felt true love. We all agree however that this is
not equivalent of saying they are psychologically normal; obviously the 60yo man is not normal by medical standards.
But the assessment about "normality" is not pertaining to a court's judgement; a judge simply won't assess if a person is normal or not, they couldn't care less.
Also the Monster of Foligno obtained generic mitigation on consideratiosn about his personality, after sexually abusing and killing two young boys. Also Rudy Guede did, and was described in rather positive terms.
So the reading of the whole statement by Massei needs to start under this caveat: the implicit premise, is that Massei is only talking about those aspects of "charachter" that matter to legal requirements for generic mitigation. Not being a previous offender is a requirement; being a charachter who could be socially rehabilitated (because young and other factors) might be a point in favor by the discretional power of the judge; the judge assumption that the defendant for some reason might feel remorse for the action is the most important factor. The concept "good charachter" here only means they did not commit previous crimes of comparable nature; it means they are not repeated offenders, cold-blood killers or anti-social drop-out kinds.
But from here to saying they are "psychologically normal", this is all about Bill William's free imagination.
