Ashley Madison was evil.
I know, that's judgey of me, and I shouldn't go hatin', but Ashley Madison was—and I suppose still is—an evil thing. The whole idea of the website, which actively encourages and facilitates extramarital affairs? Evil, if the word evil is considered to have any meaning at all. The entire point of Ashley Madison was betrayal of the trust of another person, and the active violation of a commitment you have made to another soul. Evil was their business model.
If the point of a thing is breaking a promise, and the secretive and self-absorbed betrayal of another, that's a fundamental Golden Rule violation. This odd enterprise was a creature of the dark, relying on the promise of shadows to aid in the deceiving of others, yours for just a couple of hundred bucks. So millions did, millions of lonely, bitter, jaded, horny fools.
