So, basically every verse is just Em (put some hammer ons in there), the chorus is 
G A and the bridge is Em A.

I figured out this chord arrangement for the community at ultimate-guitar.com
If you're seeing it on a different website, then you're looking at a site that's stealing content.

Enjoy! 

Em 

Em
Hordes of faces, empty eyes

I see nothing new

Seasoned schemes of slimy curs

Offer up their flu

Am I beast or am I human

Am I just like you

Power seething, really reeling
                      G
Reaching out for you
           A
Am I demon? I need to know

Em A Em A Em 

Em
Faces of a million hells rage inside these veins

Pounding out deserved pain to anyone in need

And am I beast or am I human?

Am I just like you?

Power seething, really reeling
                     G
Reaching out for you  
           A                G
Am I demon? I need to know
           A
Am I demon? You need to know

Em A Em A Em 

Em
Every world and every limb

Torn asunder base

Everything I need is me, everything I am

Am I beast or am I human

Am I just like you

Power seething, really reeling
                      G
Reaching out for you
           A                G
Am I demon? I need to know
           A                 G
Am I demon? You need to know
           A                 G
Am I demon? You need to know

  Em A
I am
  Em A
I am
  Em 
I am
