"The search for power begins when we're quite young. As children, we're taught that the power of good triumphs over the power of evil."
"But as we get older, we realize that nothing is ever that simple. Traces of evil always remain..."



trace: a mark, an object or a sign that shows that sb/sth existed or was present

evil: the force of things that are morally bad

remain: to still be present after the other parts have been removed, used, etc.; to continue to exist

I think it applies more widely than to a single person. It's like karma. If an evil act occurs, no amount of good can completely erase the evil - traces will remain in the memories of some, or in the wider effects that the act has caused.
