Rock-a-bye baby

Rock-a-bye baby, from shadows I come
Someone once told me all wrongs will be undone
Rock-a-bye baby, to all those who died:
I am here now. I'll put things right

Rock-a-bye baby, still I must kill
I am the monster that slaughters for thrills
Rock-a-bye baby, from peace comes a new war
I have returned to avenge you all

Rock-a-bye baby, there's blood on the ground
There's demons and ghosts that hunt without sound
Rock-a-bye baby, oh father can you see
What once was locked now has been set free
