Human nature itself has both good and evil tendencies.
In between good and evil, there is a huge blind spot that humans are extremely unaware of.
Humans generally behave both as a good follower and as an evil leader.
What does that mean by good follower? When a human is in powerless/helpless position, he/she will use all sorts of moral and ethical justifications and judgments on others to do good to him/her. For example, "You should treat me well/fair/equitably" or "You should treat me with kindness/generosity/love/selflessness/empathy/etc". In other words, when a human is a follower, i.e. powerless/helpless, he/she tends to 'practice' good standards and judgments (albeit on others).
On the other hand, when a human is in a position of power, he/she will tend to take all sorts of actions based on his/her own selfish interests with total disregard to any moral and ethical justifications and judgments on themselves. He/she may do something that benefits himself/herself that may also be detrimental to others, but then he/she will use all sorts of reason and logic to justify why what he/she did is right (for himself/herself), regardless of whether it is right or wrong to others, thus the meaning of evil leader. For example, "I am right to rape/steal/cheat/kill/commit sin/commit corruption/etc because of (fill in the blank) reasons". In other words, when a human is a leader, i.e. powerful, he/she tends to display evil nature.
Powerless/helpless humans do bad things with little to no empathy on others. Powerful humans are even more so.
Of course there may be humans that are thoroughly and universally good regardless of whether he/she is a powerless follower or a powerful leader, but I sincerely believe such human extremely rare, and I am speaking of the majority of humans.
But I think the most critical issue is not whether a human has such opposing (or self-contradicting hypocrite) nature, that is, being a good follower and an evil leader (also in a sense that the moral and ethical standards that he/she imposes on others are not being equally applied on himself/herself, thus giving rise to "You are wrong to hurt/cheat/steal from me, but I am right to hurt/cheat/steal from you because I have my (fill in the blank) reason and logic" kind of mentality).
Rather, I think the most critical issue is that humans in general are very much unaware (or do not wish to be aware) of such blind spot that causes most humans to be generally self-contradicting hypocrite in nature.
I believe if humans in general can be self-aware of such blind spot, then it would have a chance of being addressed, resolved, and make this world a way much better place to live in.
Because if a human can be self-aware of such blind spot, then the moment before he/she commits a violation on others (for the benefit of self-interest), he/she would think, "Hey, it is wrong for me to rape/cheat/steal/kill others and I should stop" and cease committing the violation.
If you say, "Hey, I always have such reflection when I tend to do something wrong, and thus I am actually good and not a hypocrite", well, don't be so quick to give yourself credit. Wait until you are in a position of power first. As they say, absolute power corrupts absolutely. Only if you still have such reflection can you consider yourself universally good and not a hypocrite.
In the meantime, be aware of your blind spot.
