If life is the result of some blind process such as evolution, then the terms "good" and "evil" have no solid, objective meaning, and the question, "Are Humans inherently Evil?" gets bogged down in a morass of personal meanings, and discussions at cross-purposes.
But, if we were *created* by a Creator, then there is some standard of what we are, some intent of how we are to live, some order designed into our lives. We call that "good", and the absence of that good is called "evil".
Since we are created by a Creator, and if we accept that He would not create us in a less than good state, then we are inherently good, not inherently evil.
Why do we see people doing bad things if they are inherently good? Judaism and Christianity answer that question by looking to what happened in the Garden of Eden. There God created Man in goodness, and amazingly granted Man the freedom to choose for or against goodness, and left that in Man's hands, with the warning that by choosing against goodness, Man would disrupt the goodness both within himself and all throughout creation. Man ignored God's pleas, and knowingly chose against goodness, and now we suffer the terrible consequences of that choice. But, the goodness, while *disrupted*, is not gone. We are still inherently good, but some of the goodness has been lost.
So, we are inherently good - but we have handicapped ourselves, and thus we lust after and do bad things. But we are not inherently evil.
