No, Britney's situation is one for the books on its own. It's too fresh to look back to, but in some cases I think Britney had it worse. Michael didn't mentally destabilize in the same way Britney did. Michael didn't lose his characteristics to a point that he seemed like more like a tomato than a human. The way the torture affected Britney really damaged her brain and its ordinary capabilities and she's still a tortured forced glove‐puppet because she has the responsibility to entertain. Michael had it waaaay worse in other aspects though, and some things really do look alike. The most similar thing is that they're both killed before they died
The comparisons you've named aren't all to be bragged about, but here you have it.
