I would sentance that boy to life without parole. Did our country go easy on Sasddam Hussein since he had a bad childhood?Adolf Hitler?or more down to earth Charles Manson? He had a rough life and was on LSD. It would be a little different as well if hadnt shot them multiple times and then tried to burn the evidence up and flee. He was on a SSRI antidepressant. Big deal.I take a rather large cocktail of pills a day including prozac,wellbutrin,lithium,remeron, zyprexa,clonazepam and abuterol. I happen to have quite a temper when I was on steroids prescribed to me after surgery and for my lungs. Do I blame the pharmaceutical company and say it was their fault I tried to stab a guy in the leg?No. Its pretty bad when an ANTIDEPRESSANT company has to put on their labels as a side effect a chance of suicide. No sH*t? A DEPRESSED person with a chance of suicide?
People snap me and my wife both have before. You cant blame your actions on a drug or medication because the acts you commit are acts that are in your mind to begin with not just magically transplanted there because of a pil (Disasociative Hallucinogens excluded aka PCP,Ketamine and DXM). Yeah raising your serotonin a little bit might make you edgier but you wont do anything that you werent perfectly capable of without it. He is a stone cold killer. Life without parole is my vote and thats only because he was 12 when it happened otherwirse I'd say death row.
edit:Hitler was on an unknown at the time drug Methadone as well as methamphetamines as were alot of his troops. Sure didnt excuse them from executions when Germany fell.
