Ye olde English puzzle

Are you an avid reader of literature, from shakespearian to modern? If so, I'll test you on that.

I will give you a puzzle. A rather simple one, that is. Basically, you have to find the 4 digit code, and to do that, you must read this poem. Get ready.

In here is a tragedy---
art thou player or audience?
Be as it may, the end doth remain:
all go on only toward death.

The first words at thy left hand:
a false lunacy, a madly dancing man.
Hearing unhearable words, drawn
to a beloved's grave---and there,
mayhap, true madness at last.

As did this one, playing at death,
find true death at the last.
Killing a nameless lover, she
pierced a heart rent by sorrow.

Doth lie invite truth?
Doth verity but wear the
mask of falsehood?
Ah, thou pitiful, thou
miserable ones!

Still amidst lies, though the end cometh not,
wherefore yearn for death?
Wilt thou attend to thy beloved?
Truth and lies, life and death:
a game of turning white to black
and black to white.

Is not a silence brimming with
love more precious than flattery?
A peaceful slumber preferred to
a throne besmirched with blood.

One vengeful man
spilled blood for two;
Two youths shed tears for three;
Three witches disappeared thusly;
And only the four keys remain.

Ah, but verily...
In here is a tragedy---
art thou player or audience?
There is nothing which cannot
become a puppet of fate or an
onlooker, peering into the cage.

Alright, I will give you a hint. The code is
41523. However, didn't I say earlier that it was a four digit code? Yes, go work on that one.

Alright, i'll give you more hints. "One vengeful man (Hamlet) spilled blood for two"

"Two youths (Romeo and Juliet) shed tears for three"

"Three witches (from Macbeth) disappeared"

See, I told you it was simple.

Come on, guys. This is really simple. But only if you try to actually solve it. I thought you were good at solving puzzles, no? lol

30 minutes hath passed. Dost thou still persist, on solving thine puzzle? Dost thou still persist, on ye olde, simple puzzle?

Perhaps, you may not? For have thou lost will? If thou shalt waver, then thy key shalt dissapear. Are thou player, or are thou audience? It matters not, for all go only towards death.

If by a week this still isn't solved, I'll laugh.

Alot.
