"I Have No Mouth, And I Must Scream".
I realize most might just see it as unsettling, but I've known someone like AM. Obviously not a giant supercomputer, but with that much hate. With that much blind rage, that everyone around him must suffer for daring to exist. That would happily keep someone alive just to bring them more pain.
As much as I love that story, every time I read it leaves me a little more terrified, looking over my shoulder, waiting until I'm put in my cage because I dared break free, even almost 20 years later.
