Being aware that JH was knowingly exposing people to HIV in this movie, means I cannot watch it. There's nothing sadder than a person's soul decaying to the point where one can do something like that.
Holmes knew, he didn't tell anyone, and that's very bad. I think 'morality' got a bad name when it got too associated with forbidding consensual sex; that's a shame, because one of the words we _need_ to describe what Holmes did in this case is 'immoral'.
