I love asking this question. Answers are usually in the "good" or "evil" spectrum, so everyone gets it wrong.
Human nature is neither inherently good, nor inherently evil. The thought-experiment that I like to use is the blank-room experiment. If a person is born into such a room and locked without provision of significant stimuli, all you get is a blank person. The environment is an important factor.
If humans are quite similar to computers, then the environment is our operating condition / operating system.
And indeed, we are quite similar to computers. Our operating condition creates the human condition.
You can think of cultures as operating systems, beliefs as softwares, behaviours as outputs, and life as what it appears on screen.
We are programmable.
And that's human nature.
