Lamentations of a War Machine/End Song

I've saved the human race
 By staring death right in the face
 And it's because of my bravery
 Humans are safe from slavery...
 Tell me Dr. Light
 Why did I fight?
 Tell me doctor (Tell me doctor)

 If I've a heart made of steel
 Then does that mean I cannot feel?
 Remorse for everything I've done
 My hand's a smoking gun!
 Tell me Dr. Light
 Why did I fight?
 Tell me doctor (Tell me doctor)
 Was I right?
 He walked away from the castle left in ruins
 A path of destruction in his wake.
 The clouds parted, and the warmth of the sun brought the question -

 Would this quest ever end?
 What purpose am I to fulfill?
 Was I built to kill?
 Is there a soul beneath this shell?
 And will it go to robot hell?
 Tell me Dr. Light
 Why did I fight?
 Tell me doctor (Tell me doctor)
 Was I right?
 How many must fall until there is peace for all?
 Tell me was I wrong before we get to the end of this...
 This is the ending song

 This is the ending song
