Rabbi Avigdor Miller said he did the right thing. nevertheless there was a very small lack in his Emuna, and for a man of his greatness, there needed to be punishment. he also states that his death was a KiddushHashem for it demonstrated the great sanctity of the Aron, and he was certainly rewarded for this in OlamHaBah.
if you find some contradictions in the above, it is not a quote but only my memory of what R’ Miller said, and please attribute any innacuracies to my faulty memory
