Google: See no evil, do no evil

If Google views all their actions through telescope vision and never allows themselves to enterain the thought that what there doing maybe bad, can they ever do evil?

I watched the google documantary not to long ago, and when the questionaire started throughing Marissa Mayer (the Product manager at google) some obivously tough questions about Google Books and the possible effects of their actions, here response several times was simply "I don't see that way".
