@ThatMatsuri  I think here brother means like all the angels are brothers type brother as the other angel also referred others as brother
And here he is not blaming himself because of his brother's sins( Lucifer's ) but because Lucifer did all  that because he loved him so much
I don't really know I am just guessing 
 I was wrong they were real brothers  so yeah you were right and that's little...
