Equity in sins

Can equity be truly achieved? I don't think so. The ideology is perfect, however to an extent, it lacks credibility. The establishment of equity aims to eradicate all forms of stratification: wealth, intellectual, racial, occupation.... Through this, equity achieves a fortitude of peace, harmony and stability. No matter how idealistic this concept, it is not applicable to humans. As for humans, I do not think we can fully achieve equity, however, humanity is somewhat heading in the right way, with the influence of sins. Mankind are infiltrated with all forms of sins, to name them: wrath, greed, sloth, pride, lust, envy and gluttony. Our susceptibility to such sins and immortality makes us more human as compared to our morals and ethics. It is true, ethics and morals make a person better. However, without the immorality, flaws and sins, people will not be considered to be human. We transcend to a divine level, or in scientific views, we degenerate into societal robotic that strictly complies to the laws of society, complying to what god and people assume to be right.  This consequently results in a conformist society; society will be stagnant, people will not see or view the need for changes as they think of their society, their morals and their beliefs so well. As a matter of fact, with sins,  people want change and people will try to force it to happen. Let's say in the case of equality, it is greed that makes people want equality. Without that, people will still be blindly living in society without equity.
