Dave Hanson, this raises the interesting question of free will doesn't it? I (and presumably you) have not got drug habits and don't burgle, steal or commit crime. I expect you would say we have chosen to be law abiding, and the criminals have decided to go wrong. But WHY have they decided that? In many cases, they have been dragged up on sink estates, with no parental role-models of any worth, surrounded by villainy from day one. Drugs are a part of life there, and of course necessitate theft to fund them. These are not excuses, but REASONS. I don't condone their evil acts, I'm merely academically interested in whether they truly have exercised free will, or are reacting to unavoidable circumstances in their genetics and early lives. I remember discussing free will in Moral Philosophy at Uni (a long long time ago), and it's a tricky thing to nail down.
