Suppose I ask you to refrain from kicking me in the nuts and you then kick me in the nuts.
The next day, you are in an unfortunate position, and noting this, ask me to refrain from kicking you in the nuts.
But I, remembering how unpleasant I found your kicking me in the nuts, decline your suggestion and kick you in the nuts
This DOES NOT MAKE ME A HYPOCRITE. A Nut-Kicker, yes, a sadist, perhaps, but NOT a hypocrite.
No matter how much your nuts hurt.
No matter how much anyone's nuts hurt, actually.
