This is about Adam being the father of mutants and Mutant x

Adam

How could I have hurt you all?

Even when you were all so small.

I can't look into their eyes

So I tell them all these lies.

I will protect those in need

Those who I will vow can be freed.

No one should feel your pain

I will make sure, never again.

I can't even think to let you all go

Perhaps a bond we all made long ago.

I can't stand to see you all in pain

So the mutations I try to sustain.

Helping you all control your wild gift

Ever time I see you the weight on me will lift

The weight will lesson each time I see all your joy

That is the one thing, I promise not to destroy.
