Yes, this is a sufficient penalty. For all intents and purposes, a 45 year prison sentence is a life sentence. Even if you were to get a 45 year sentence at the age of eighteen, you would not be released until age 63. At that age, you only have a little bit of time left.
A Michigan doctor was sentenced to 45 years in prison for giving chemotherapy to patients who didn't actually have cancer. This is a sufficient penalty, he probably will not live to see the end of his sentence. He should also be forced to live on bread, water and vitamin tablets
A Michigan doctor that was sentenced to 45 years in prison actually got off easy. He gave chemotherapy to patients that did not have cancer. Essentially, he poisoned those people unnecessarily, doing damage in both the immediate and long term. There was also the psychological impact on the people that thought they had cancer.
The harm that he caused the patients who received the chemotherapy is probably going to stay with them for the rest of their lives. A life sentence is what this doctor deserved. He will probably appeal the case and possibly get released early while his patients will be spending thousands of dollars and years of their life visiting new doctors to repair the damage that he did to them, if it's even possible at all.
