Why are lies, deceit and deception so prevalent?
Because they are helping us to get what we want. And they are useful tools if we need to get off the hook.
So, why do we despise these excellent tools?
Because we have to pretend that we don't use them, otherwise they wouldn't work.
We have evolved to survive. To be honest and playing fair will only cause problems for you.
