Hypocrisy is the contrivance of a false appearance of virtue or goodness, while concealing real character or inclinations, especially with respect to religious and moral beliefs; hence in a general sense, hypocrisy may involve dissimulation, pretense, or a sham
I'd liken hypocrisy to an autoimmune disease of the mind since its a continent act of self discipline and self destruction. I view hypocrisy as a serious plaque on the mind which overtime, can lead to a fantastical sense of perfection and shift in sense of judgement.
How it works isn't as complicated as a nuclear theory; it seems the mental pupil off the victim delates and enough light gains entrance into their mental eyes enabling them to vividly X-ray the wrongs in other people's action while they develop mental cycloplegia towards their very own.
If you did the same thing in the past, why criticise he who's doing it presently? No man is qualified to judge another man. I rest my case.
