Cover art for Black Sheep lyrics by August Burns Red

I might be wrong, but I think this song is targeted at someone who only cares about himself and his philosophy that he is the only person that matters.

The line "pain must exist in order for healing to survive. Neither one will ever serve their purpose alone" is saying that life can't always be one way. You gain some, you lose some. You have to compromise sometimes because life isn't a one-way road.

But this person has been so in love with his belief and narcissism that it's too late and everyone has already given up on him.
