Lucifer's damage was physical; Michael's was psychological. Michael was essentially punished for doing his father's will, which he dedicated his whole life - billions upon billions of years - to following. He was caged, like Lucifer was, but for the opposite reason. Lucifer may have been betrayed by God in some ways, but Michael was downright abandoned and left to rot in a cage meant to contain "a monster", as Michael put it.
