We will always have the ability to do evil and be evil and through the possibility, it will continue to exist on a level of consciousness. But we must first experience it to overcome it. Yes, then which states of human behavior or consciousness came with us and which traits didn't. You also say, I don't see anything that God is given credit for at creation that could be thought of as bad or evil. Now that sounds silly at first, but it makes sense to me.
Sure evil is our creation, but so is the the conception of good.
I am not saying that evil is OK and we should except it, I am just saying that evil is part of all of us, and is no different than the good characteristics that we all have as well. What separates us from nature, aren't we natural. Now maybe there are some people who still need to hunt in order to exist, but for the most part, we Americans have NO justification to hunt, and to senseless kill another animal when every grocery store in the country will have meat that must be thrown out and wasted every night. We don't need to kill more, yet we do and feel good about it. It seems to me that you are trying to retain the creation story of the Bible.
