I think people are inherently "good"; we evolved as a social animal, banding together to help one another, safety in numbers and all that. If we were born "evil" then I doubt that would ever have happened. There have even been studies done with showing that babies understand altruism [http://psychcentral.com/news/2011/10/11/young-brain-has-altruistic-characteristics/30233.html]. I think "evil" stems mostly from how a person is raised and exacerbated by certain genetic defects and as such people are, on the whole, good.
It's easier than you'd think to hold that view and still be misanthropic.
