I think humans can make a choice. The heart can contain good and evil and give out what a human being desires. All humans have knowledge of what is good and what is bad.
However, Before we start to debate if humans are inherently good or evil, We need to define what is good and what is evil.
Good and evil is a myth created by humans so that they can cope with things they don't like, Disagree with, Etc. Now if were talking about your moral standpoint of good and evil, You would have to define it first before you resort to good and evil. If your looking for someone else's opinion, And based off of my moral standpoint. I try and view nothing as evil and nothing as good, But just actions happening for a reason. Its a bit nihilistic but I hope you develop your own thoughts.
