It depends on the perspective from which you’re asking the question.

Here’s a question from a sociological perspective:

What laws, policies, and programs would lead to fewer people developing drug addictions and engaging in theft to obtain drugs?

There are answers to those questions. We know people with stable housing, good jobs, strong social networks, and mental health care are less likely to get addicted to drugs and commit crimes to fuel their addiction.

Here’s a question from an individual perspective:

Should Johnny be punished for cutting catalytic converters off other peoples’ cars to fund his meth habit?

I think most of us would say yes, even if he wouldn’t have developed the meth habit if his life didn’t suck due to factors beyond his control.
