I think anyone who drives drunk or under the influence of any drugs is a scumbag. Addiction is a disease, yes. But after you've endangered the lives of others on multiple occasions (and faced little to no consequences), I just can't have much sympathy for you anymore. You could end up killing someone. It happens way too often and it pisses me off. So many innocent lives lost.
Celebrities and people with money always get off too easy for their crimes.
