These "don't be evil" and "do the right thing" must have been taken from the well known buddhist story: "When a disciple approached the buddha, he asked to explain buddhism in one verse; the buddha answered: stop doing evil, start doing good and clean your heart - that's the religion of buddhas."

However google here is that junkie who tattoed buddhists scriptures on his arms, but never bothered to live by them. He did the "don't do evil" tattoo when he was devising a plan to rob a monastery. That was his inner self tried to stop him. When he decided to take hostages, he added "learn to do good". Shortly before he decided to build a torture chamber, his inner self made the final attempt and made him do the "clean your heart" tattoo. Corporations are soulless creatures, and can't tell what's good and what's evil.
