Zgirnius "He really has been acting as a double agent in LV's camp for
DD, at considerable risk to himself. BUT, he takes a gamble in Chapter
2 and loses."

Jen: "Jen's response: But I think Snape might have known what Draco's
task was..."

We all agree that Snape is smart; if he agreed to that part of the
**Unbreakable** Vow without knowing what he was getting into, then in
fact we're all wrong and Snape is really, really stupid. 

In our world, double agents are never trusted. Never. Doubles have a
way of turning back on their defections for a variety of reasons, and
often learn enough to keep their heads if they return. Someone who
defected once can defect twice.
