The song Rectifier, in my opinion, pertains to someone who realizes that they've been in bad relationships before, and they're driven to anger and guilt by what they've done. But, at the same time the 'narrator' can't let go of what the other person has done with their lack of compassion and willingness to connect with them (the narrator).
Unlike most songs on the album that this song is on, the narrator is singing about both sides, because both of them have the same problem: an unwillingness to let go of their painful pasts, because that's what they continue to see in their current partner. They're under the perception that the other person is both rectifier and wrongdoer.
