Is human nature good or bad?

     We are not talking about practiced behavior...we are talking about human nature. People are not robots. They have the ability to distinguish between wrong and right. Yet we all choose to do what is wrong more often than not. People know it's wrong to gossip, but they do it. They know it's wrong to take advantage of others, but they do it. They know it's wrong to lie but they do it. They know it's wrong to take things out on the people they love, but they do it. Ask yourself why.
     But isn't it also in our nature to do good? Isn't the feeling of warmth you get in your heart when you share or do something positive universal to all of humanity? If so, how do you quantify which we do more often than the other?
     You seem to be saying that the stuff that comes from within us is all bad, and the only reason we have any good in us is that the good comes from outside of us. But where does the stuff outside of us come from? Isn't human society a product of human nature? And if so, doesn't the good stuff in society come from human nature just as surely as the bad stuff does? If it (the good stuff we learn from society) doesn't come from human nature, what's the source of it? What's the source of society's goodness if not human nature?
    In conclusion I don't think that human nature is good or bad. It's a little of both.
