@ahmedjbh,
Hey there,
I don't think you've supported your statement that humans are inherently evil. I think most (if not all) humans have that
ability, as you've loosely defined here. But that's a far cry from saying that they
are. Two different ideas
Although I'd agree that most of what we call evil probably does include selfish motives, that's not to say all acts-of-the-self are evil. Nor is good necessarily an act of
selflessness. Selfishness isn't necessarily Evil.
To say that 'Evil exists because someone could perceive something, based on their perspective, to be evil' is disjointed. If Bill says I have an Avacado as a left hand, should we then say then that "human have avocado hands" and then embark on a debate about the "why"?
I'd also disagree that humans are born with the idea of putting others before ourselves. Isolate someone for their first, say, 20 or so years then toss them into a group of people and I doubt you'd see much of this. I'd agree that it's a tendency, propensity, but not an innately-borne aspect.
Hope this adds well to the discussion
