Hahaha, this is about you

Beware, beware, be skeptical
But their smiles, their smiles are plated gold
They seem so natural
But a wolf in sheep's clothing is more than a warning

Bye bye, black sheep, have you any soul?
Closer, by the way, what the [bad word] are morals?
Jack be nimble, Jack be quick
Jill's a little [bad word]  her alibis are dirty tricks

So could you
Tell me how you're sleeping easy
How you're only thinking of yourself
Show me how you justify
Telling all your lies like second nature
Listen, mark my words, one day
You will pay, you will pay
Karma's [bad word] collect your debt

Oh well, oh well you stalk your prey
With criminal mentality
You sink your teeth into the people you depend on
Infecting everyone, you're quite the problem
Fee-fi-fo-fum, you [bad word] and hide
I smell the blood of a petty little coward
Jack be lethal, Jack be slick
Jill will leave you lonely dying in a filthy ditch

So could you
Tell me how you're sleeping easy
How you're only thinking of yourself
Show me how you justify
Telling all your lies like second nature
Listen, mark my words, one day
You will pay, you will pay
Karma's [bad word] collect your debt

Maybe you'll change
Abandon all your wicked ways
Make amends and start a new again
Maybe you'll see
all the wrongs you did to me
And start all over, start all over again

Who am I kidding?
Now, let's not get overzealous here
You've always been a piece of [bad word] 
If I could kill you I would
But it's frowned upon in all fifty states
Having said that, burn in [bad word] 

So tell me how you're sleeping easy
How you're only thinking of yourself
Show me how you justify
Telling all your lies like second nature
Listen, mark my words, one day
You will pay, you will pay
Karma's [bad word] collect your debt
