I find that my students work better on questions of ethics when you supply them with concrete case studies — so when I read the first bit of this story about Pete Doherty, I immediately thought about it as an example relative to questions of truth-telling and fidelity. But the more you linger with it, the more ethical plot lines come to the fore (especially as you read on to the end of the piece). You could devote an entire semester to teaching the ethics of this narrative.
