It's also the individual's responsibility not to ruin their lives with drugs, or develop heart disease due to poor diet and exercise. People on average have poor impulse control for anything that's even a little addictive. I'm not suggesting that regulation is the answer here, or always the answer. But, the case of moral blame is not the same as describing the problems of large portions of the population. So what if we all agree it's the individual's fault that obesity has been on the rise for decades? Does the blame here modify the severity of the problem, or prescribe an outcome? How useful is moral blame really, when it comes to societal problem?
