The Fates of Undertale

We, three fates of UNDERTALE
Beckon you to play
Spare our lives or harvest our souls
It's up to you either way

Hey bud', you okay?
Oh, no need to freak out or anything
It's just singing
And murder! ...Ha ha, I mean: music
Poor dear. We're here to help you
(Help me what!?)
Play UNDERTALE!

Use your love
Instead of your strength
To make your foes your friends
Every drop of innocent blood
Will change how the story ends

Though our king desires your soul
A pacifist will see
It only takes a thoughtful act
To set all monsters free!

(No pressure or anything)
(Yeah, huh, real freedom is not like some goat mom tells you how to play)
Excuse me?
(Hey, if anyone's got a bone to pick...)
(I'm sure this kid is full of them)
(That's not funny!)
(Yeah, I get that a lot)

Still you seem nice
You may slip once or twice
Who am I to judge or blame?
But I guess I'll keep track
Just to give you some flak at the end
Of the game

Talk or use silence
Try murderous violence
Hah! I'm kidding. That's a crime
And just so you know
If you kill off my bro
Then you'll have... a bad time

Golly gee, that sounds really great
But let's try this instead!
Let's become the Angel of Death
And make every monster dead!

Kill them all, destroy every beast
Each woman, child, and man
Genocide's my only goal
Destruction is my plan!

It's kill or be killed! (No! He is trying to use you, so...) (Look, I'm kind of a bonehead)
That's how you play the game! (don't let Flowey confuse you! I know...) (Not the brainiest guy, but...)
It's kill or be killed! (he aims to seduce you) (even goofballs like me can...)
Either way, it ends the same! (and ruin UNDERTALE!) (read between the lines)

Everyone you loved... (Stay determined! They will guide you astray!) (If you want to get dunked on...)
Everyone you knew... (I know that you'll be lied to; you're brave) (I can give you a hand)
Everyone will die! (I can see it inside of you!) (But where's the fun in the neutral run...)
And they will die because of you! (I pray you will never fail!) (if you're not friends with Sans?)

(None of this makes any sense to me!)

We, three fates of UNDERTALE
Don't know what you'll do!
Every path will impact us all
For better or worse...
A blessing or curse...
Benign or adverse...
It's up to you!

(Oh sweet! Someone just gifted me Rocket League!)
