Questione giuridica chiave
Whether the 20-year prison sentence violated Art. 63 CP by failing to consider personality disorder, remorse, conduct, and young age.
Decisione estratta
No. The cantonal court considered the relevant mitigating factors and did not abuse its broad sentencing discretion; the sentence was not excessively severe.
Motivazione estratta
Only disorders affecting criminal responsibility matter for sentencing in this framework. The psychiatric findings did not reduce responsibility, and the defendant's youth, difficult childhood, remorse, and detention behavior were acknowledged but did not justify a lower sentence given the gravity of the crime and high recidivism risk.
