Okay, I just depressed myself before bed

I looked up the translation for this one Fullmetal Achemist song that's in Russian. And now I'm sad:

Forgive me, younger brother
I am so guilty before you
It is forbidden to try to regain
That which the land has taken

He who knows the Law of Genesis
Would have helped me to find the answer
I was cruelly mistaken:
There is no medicine for death

Dear mama! How tender!
We so loved you
But all our strength
Was for naught

I tempted you
With wonderful hope
To regain our family hearth
My brother, I am guilty in everything

Don't cry, don't be saddened, older brother
You are not the guilty one
We have but one road
We will atone for this guilt 'til the end

I don't accuse you of anything
And I am not offended in the least
A burden, our sin
Of wanting to be stronger in everything

Dear mama! How tender!
We so loved you
But all our strength
Was for naught

I myself was tempted
With wonderful hope
To regain our family hearth
I myself am guilty in everything

But what are we to do, how to be
How to repair everything, how to forget?
It is forbidden to try to regain
That which the land has taken
