I guess I'm assuming that if murder is being the charge considered here, then it is likely the child is showing no remorse
That is not correct. A charge of murder requires intent. CLEAR intent.
Read the law. Murder involves going out with the intent of killing someone.
Otherwise, everyone would say 'I'm sorry' after and avoid charges of murder and longer prison sentences.
Even if someone is angry at someone or dislikes the other person, that is not INTENT. It MAY be part of intent, possibly, but generally, no.
INTENT means you wake up in the morning, buy a gun, tell your friend, 'I'm gonna kill that SOB today', and you go out and shoot that person in the head or heart and he dies.
Two guys are drunk, and they start playing around, smacking each other. It escalates into an argument. Things get out of hand. One person winds up dead. There may be many charges and a long, long jail sentence, but murder may not wind up being one of the charges.
In the public mind, 'murder' equals 'killing someone'. In the legal system, the word 'murder' is a very specific charge for very specific conditions.
Charging someone with murder or not, generally has very little to do with whether they act sorry afterwards or not. It's all about intent.
Additionally, there are different degrees of the murder charge, as well as modifying circumstances that can lead to an EVEN LONGER sentence. Such as murdern in the process of committing another felony.
People CAN get charged with a good many OTHER charges and the sentencing guidelines for THOSE charges can add up to an awful lot of years in jail. It isn't like someone 'gets away with it' if they are not charged with murder. There are many, many other possibilities of what they can be charged with. The legal system is logical and flexible enough to allow for different situations.
Our laws recognize that people very often kill someone without actually having clear intent to do so.
A man I know got seven years for killing someone. I am not sure what the charges were. He did get seven years. He was robbed. he left the scene, went to his house, got a gun, and walked back, and shot the guy that robbed him.
As much as a good many readers would go 'yay! That's justice', people don't actually have the legal right in this country to make themselves judge, jury and sentencer. That's vigilantism.
The judge was put in an extremely difficult position. What he did was give the guy the minimum he could under the circumstances. He wanted to be clear that the guy had no right to become a vigilante, yet still take into consideration the situation. The judge did the best he could. Judges can't just make up their own charging and sentencing guidelines, they have to follow the law.
