Matt Murdock also became possessed by the Beast as a result of his selfish and ill-advised actions- does that mean that Matt should have to pay for what he did under the Beast's control and shouldn't be an Avenger? Is there a difference between the two situations? I'm not sure.
Yes, Daredevil also murdered an Avenger and got away with it, and nobody's calling for him to die. And the public actually knows about that one, while the truth about Disassembled and House of M has been kept from them.
And while we're on the subject, wow did "Shadowland" go off the rails. A potentially-awesome tale of "Is Daredevil playing The Hand like Tetris, and trying to destroy them from within, or has he finally snapped and gone completely crazygonuts?", and no, he's just being possessed by Hank McCoy.
