I've been riding the "you can't do evil that good may result" hobby horse for years. (I just googled a Bitnet message I wrote in 1993 that ends, "Good ends do not justify evil means, before, during, or after the fact.")
It's been only in the past week, though, that I've come to see that it isn't just that a lot of people think you can do evil that good may result (a thought that is only possible for people who don't know what the word "evil" means). It's more than that.
A lot of people think everyone thinks you can do evil that good may result.
And, having established what everyone is, they are merely quibbling over the price.
