Who sings this and whats the song name?

Please accept my apologies, I wonder what would have been.
Would you have been a little angel or an angel of sin?
Tom-boy running around, hanging with all the guys.
Or a little tough boy with beautiful brown eyes.
I paid for the murder before they determined the sex,
choosing our life over your life meant your death.
And you never got a chance to even open your eyes,
sometimes I wonder as a fetus if you fought for your life.
Would you have been a little genius? In love with math?
