ok, i was gonna vote evil outright, because i dont think we're intrinsically good, but then i thought - well, we're not intrinsically evil either!
viddy said it. we are at base selfish creatures. we want whatever it takes to make us happy in our few short days on this ball.
so hate me if you must, but I'll give you my religious rundown.
[You've. Been. Warned!] I will, however, for the reader's sake, try to keep it basic, and not get technical (read: biblical), so I'm going to over-generalize in a great way. If you want to get technical, by all means, but I dont want to bore.
Religious Rundown:
Us
We are neither good, nor evil. We are not intrinsically bad, nor are we intrinsically good. We just are. And in being, we crave what makes us happy, what makes us feel good. Self-gratification, if you will. This, in itself, is not a bad thing.
Super-Beings
Layer on top of that, those Super Beings that Mark_F alludes to - call them what you will, Good/Evil, God/Devil, whatever. In being, the Super-Beings personify good and evil, and exist on two sides of the moral continuum.
d/Evil
This guy represents all that is bad. Purpose being to get you to do what is bad, or to do bad things. So no. You are not intrinsically bad, it is just that you have self-gratification desires on your mind. The purpose of d/Evil is to engage your self-gratification desire to do anything/everything it wants, even at the expense of yourself, and the people around you. Thus,
[as a Very Basic Example], you have people who dont really want to die, but they kill themselves with drugs, alcoholism, etc. Self-gratification drove them to kill themselves. Why? It felt
good, baby!
[It reminds me of the theme song in True Blood, where the guy sings "I Wanna Do Bad Things to/with You!" Bad? yes. But it'll feel so good!]
Go[o]d
This guy represents all that is good, orderly and decent. Purpose being to get you to think about your actions, and tailor your behavior to behavior that will benefit you, society at large, etc. So no. You are not intrinsically good. [
Necessary Technical Digression: A believer would argue tho, that we are given a piece of God's being, called a "soul." An individual soul exists in us all, and that soul will always identify with Go[o]d, and want to do the "right" thing, even if it goes against the human principle of Self-Gratification.]
The Bottom Line
There you are, plain old you, and you just
wanna become/do
[insert your d/Evil] because it feels good. Something inside [Go[o]d?] is telling you that's a bad idea, or at the least, its gonna hurt someone, even if that someone is yourself. You know it is. You know it will. And you dont want to do anything bad - not really. You just want to enjoy yourself. Doggone it, don't
you deserve to be happy???
This is the struggle between Go[o]d and d/Evil. Make yourself happy* or do the "right" thing. Because at day's end Go[o]d is really nothing more than self-sacrifice, and d/Evil is as small as making yourself feel good,
at cost.
*I do not mean to suggest that happiness is a bad thing, or that it is intrinsically wrong to be happy, or to make yourself happy. That is not my point. I mean to say that Go[o]d, or "the right thing" is often sacrificed for personal happiness, and that, my friend, is d/Evil.
