I think this song is about someone was hurt emotionally by someone else and now this person wants revenge. They think that by seeking vengeance against the other person and by being angry, it will make them feel better. But, they soon realize that it doesn't make them feel any better. It just traps them in a torrent of anger. I think they also try to see it from the other persons point of view ("Maybe you've been wounded too, Maybe all this was your self protection") like maybe they think that the other person only hurt them to make themselves feel better.
