explanation of lyrics

these opening lyrics to the song "The Unforgiven", by Metallica.  You cannot get more plain with the meaning.  The situation of new life on earth being dominated and broken in to the system of obeying satan and his demons without objection.  He can no longer think for himself, and is deprived of his will.:

New blood joins this Earth
And quickly he's subdued
Through constant pained disgrace
The young boy learns their rules

With time, the child draws in
This whipping boy done wrong
Deprived of all his thoughts
The young man struggles on and on, he's known

Ooh, a vow unto his own
That never from this day
His will they'll take away
