This line annoys me.

To me, that line has a different meaning.

I think it isn't about self-pity. Before, he had to dehumanize his victims in order to accomplish the things that he did. Relating himself to them means destroying this protective barrier and finally being able to see them as human beings, thus acknowledging both their suffering and the truth behind his actions - which is that he is a messed up, broken man who acts on inner impulse, and not a harbinger of justice as he liked to imagine earlier. It takes effort to do that, because nobody likes to see themselves as an evil person and a murderer.

Essentially, it is a statement of remorse.

But even setting that aside, I simply hesitate to compare subjective experiences.
