I don't think that if one drinks alcohol and/or smokes marijuana that fact alone automatically makes them a "bad" person.  As for the "bad company" hypothesis, lots of good people spend the better part of their lives"p "hanging out" with bad people. I'm not religious - at all- but for of those who are I present:  Jesus.  Mother Theresa and others. Then there are the every day good people who feed the homeless - many of whom are not if sterling character- engage in round the clock social work, work with and support teens, parents, addicts and others whom society deems "bad." Having said all that, I agree that it has yet to be demonstrated that the young man was angelic.  In fact a lot has yet to be known about this case and I'm not a fan of the rank speculation such as we so often see in the comments section, especially when someone has been accused of a crime.
