Drug addiction is also an illness
Saying it's an illness is a cop out to admitting it's your fault. Would you believe a pedophile if he/she said they had a "illness"? No.
And someone who has an illness would try to seek help. Not leave rehab after a week two months ago or cancel an entire tour because "she seemed completely out of it."
I personally don't like her music at all. She may have had a talent, but it's wasted with drugs. Because taking drugs is a personal choice. No one made her smoke marijuana or stick that needle in her arm. It is an addiction, but I assure you that no one forced her the first time and no one made her continue to do it.
Society will benefit and suffer from this death. 1) There will be no more assaults caused by this deranged woman and 2) drug dealers stand to lose 25% of their business.
