"We're going to need a lot of hydrocarbons for a long time, and we'll be very glad we've got them." ... "Believe me, Chevron is not an evil company," he added. "I have no compunction — in the least — about owning Chevron. And if we owned the entire business, I would not feel uncomfortable about being in that [industry]."
