You've made a few good points that I'd like to address.
What is a "good person" indeed? In my personal view it's someone who not only refrains from harming others, he/she endeavours to do good to others, primarily his own kin (provide love, education, shelter and sustenance), then his neighbours / friends (affection, assistance), and, if possible, the community (assistance, relief, community work) where such person is inserted. Therefore, a "good person" isn't a flawless person. Such person may have inconsistencies, even outright contradictions and weaknesses. But that person at least tries to overcome or mask its own shortcomings for the common good. The broader and more inclusive are his/her efforts to encompass more people, the better that person is. This is my general notion of what makes a "good person" - it's my idea of it, it's subjective and not everyone will agree with it, of course. Works for me, at least.
I think it's an interesting notion that the way we balance love with power with justice with wisdom, and how we use pride and humility as wheights, defines us as people. However, there are other factors at play - such as mental impairments, emotional damage, upbringing, etc...so it's far more complicated than that.
As for "self confidence" and "insecurities", I agree that they have an important part to play, and help explain how some are inclined to act in compliance with an authority, but i think you've missed an important component of the said study:
The study mentioned in the Article is a Prime Example of this.. The Test subjects that were responsible for Increasing Voltage at the request of the Supervisor, did so because they were insecure and they feared dissapointing the Instructor.
While the above is partially true, you should also notice that those who believed in the superior value of science were also the ones who were more keen to inflict pain on others in the name of advancing scientific knowledge. That had little to do with fear and insecurity - it had to do with a creed in the intrinsic superiority of a cause [in this case, science]. They were willing to inflict a potentially deadly voltage discharge on the test subject because they believed it would help advance the superior cause they believed in. The more intense was this belief, the less objections they posed in administrating suffering to others.
