I am going to extend O'Tink's information for you by adding that ultimately, I think we don't even HAVE a choice between good/evil...because I have totally bought into the Buddhist stuff that the true nature of humankind is completely pure, and cannot be defiled. Ultimately there is no duality of man; we will all choose the good.
But what you CAN do is drop the Hope diamond into the sewer, so it is covered over and stinking. However all you have to do is lift it out, wash it off and voilà, there you are. And even there, our essential purity can erupt at any time...the story from Vietnam of the three soldiers, 18, 19 and 22...in their helicopter, saw a My Lai-style massacre going on...these three babies, trained to kill, landed and walked between the U.S. soldier-perpetrators and the villagers their victims...stopped the massacre...
One of these three was living in the Skagit in Washington State 1998, and the newspaper interviewed him, "You could have been killed in the rampage, why did you do it?" Former soldier smh, "I don't really know...I just couldn't help it."

Here as illustration for you is a photo with the caption “Soldier, trained to kill, mesmerized by the beauty of a butterfly.” Oh...btw, a Christian rendering of our purity is "Don't hide your light under a bushel."
