You are the one who gave it all its traits
You are the one who told it to attack and kill
You are the one who made this
You are the one
Now tell me if you are the one who's created such a creature
Why don't you see it's beauty
Why don't you claim it as your own
Why don't you love it
This so called monster is you
It contains all of your traits
It attacks and kills who you want it to
It's all of you
So I guess the deeper question is "why are you such a monster?"
