> Dumbledore also trusts another powerful wizard who demonstrates pettiness, childishness, and immaturity: Sirius Black (still using the
schoolground nickname "Snivellus," still wishing that Severus had died in the so-called Prank, etc.).

Dana now:
Why is Sirius Black always dragged into the conversation to prove DD could not be wrong about Snape?  DD was wrong about Sirius actually, but acted nevertheless on it by taking Harry out of his care. And this was before the confrontation with Wormtail. Apparently DD believed Sirius was capable of betraying James. And even if he did not believe it at that moment, he did not trust Harry could be protected by Sirius and decided a blood protection was the only way, and without consulting Sirius, I might add. He also did not believe in Sirius enough to ask him what happened. This so-called trust you believe DD had, only occurred after PoA, when DD was proved wrong about his judgment.

Also, Sirius never says he wished him death. He says it serves him right, after Lupin states Sirius thought it would be amusing to tell Snape how to get past the WW but before Lupin mentions he could have run into a fully grown werewolf.

If Snape got killed because he could not control his own curiosity, it would technically not be Sirius's fault.  It was Snape's own choice to go in, after he was told how. Do you really believe that Snape would not understand that there was a very specific reason Lupin was left there once a month? If it wasn't anything serious, then why hide him in there? We are to believe Snape was so clever and a genius in the same year (the scribbles in the book) that the "prank" took place, but he was to dumb to understand this?

Carol:
>Clearly, Snape's inability to get past not one but two humiliating incidents, the "worst memory" and the much more dangerous and traumatic exposure to a werewolf, followed by the humiliation of having his life saved by his worst enemy) is not a reason to mistrust him in DD's view,

Dana:
And here, I believe, DD made a huge error in judgment because Snape IS driven by his inabilities to get past the past.  He tries to get Sirius's soul sucked, guilty or not, for betraying James or killing Wormtail and 12 muggles. He breaks a promise to not tell Lupin's secret, and this action even gets a ruling in place so Lupin can't get any work. He can't teach Harry Occlumency, something that is so important, that it should not be dependent on Snape's hurt ego and even indirectly causes Sirius's death. Someone driven by his past pain IS a danger to anyone that rubs him the wrong way. He is even more a loose canon then Sirius because he only wants to risk his own life, not that of others.
