I used to have a pretty simple understanding of this. Lying is wrong, and that's just that.Anyone got any ideas as to why we humans presume this, or how it become "a moral thing"?
One experience that gave me a much more nuanced view was facilitating a HIV/gay support group in a smallish city. I am fairly well known around here, and facilitating the meeting wasn't a secret. As a result, people would occasionally ask me questions about other people that was utterly and absolutely none of their business. Like "I heard that so and so has AIDS? Is that true?".
Well, on the one hand, I wouldn't be lying if I said something cagey like "You should ask them yourself." But I also knew that it would be taken as a "Yes". Especially when it was true. And it was my job to protect people's privacy. So I learned quickly to lie. "No! That's an ugly rumor that isn't true. And I would know because I facilitate the support group."
On the one hand, some of the regulars weren't just HIV positive, they were also sleazy. Lying about your status was common, specifically to get laid. That put other people at risk. If someone took my word, and got infected, it would in a way be the result of my flat lie. But in a way it would be the result of things way beyond my control, like having risky sex.
On the other hand, I was also committed to protecting people from the gossip mill, and all the trouble that causes.
I had to decide what was the right thing to do, which I decided was to tell dangerous lies. Because I decided that my task of protecting people's privacy outweighs protecting every sleazeball from contracting a fatal illness.
But that was really hard for me.
