and needs a serious evaluation to determine if he is a psychopath and if he is...no release just a transfer
If he is a psychopath, it might explain his behavior. However many psychopaths are functioning, contributing members of society. Some are CEOs or large corporations. (Psychopaths tend to rise to the top in a dog eat dog capitalist society because they tend to be ruthless.)
Lacking a sense of empathy for others (psychopath) combined with a blatant disregard for the consequences of actions can lead to deadly consequences. Based on the excessive number of times the youth stabbed his victim, I'd say he also has severe anger management and rage problems. A maximum security mental institution where he would be held until a qualified expert deems him safe to release might have been a better judgement. But the judge determined that a prison for adults was the correct venue for his rehabilitation.
Judges should be free to exercise judgement without political interference.
