Alcohol is too ingrained in human culture and history as it's likely as old as civilization itself and had numerous purposes (i.e. not only for pleasure) throughout the years.
As for the blame - for me, it's solely the fault of an individual as long as it's a grown up with knowledge of the potential harm of misuse. Let's be clear here, the overwhelming majority of people in the world using alcohol do not abuse it or misuse it to such a degree where it has an impact on their daily functioning and the well-being of themselves and their families. Some are more susceptible to become addicted, but it normally takes years of abuse to get there and if said individual doesn't realise the problem and doesn't accept help, well I'm not sure we can blame anyone else can we?...
There's a difference between drinking moderately and getting wasted like an Englishman on a stag do abroad too haha. The former is shown to have certain health benefits, the latter is destructive.
