Earlier quoted context omitted.
"Don't be evil" is perfect because of how simple it is. It's supposed to be common sense. > people can have significantly different ideas of what counts as evil. And those people, who need someone to explain to them what is or isn't evil, aren't welcome. That's why I personally loved that motto. Too bad that whole ethos got dropped like it was a recently-launched product.
This topic fascinates me, but I haven't found a way to productively discuss it on HN. If you too find it interesting, you may enjoy doing a literature search on the topic.
Do no evil seems stricter than don't be evil. How much evil can you do before you are evil? Or can you be evil while doing no evil?
