Snape's purpose in GofF

No: HPFGUIDX 34663

Everyone seems to take it as a given that Snape will be a spy and 
Voldemort will let him, but what if Dumbledore has a totally 
different plan?

We know the Dark Mark is a link between Deatheaters. As one of 
the 'Great Wizards' deemed worthy enough to be on chocolate frogs, 
what if Dumbledore developed a totally unexpected spell?

How about if Dumbledore cast a spell on Snape's Dark mark giving him 
a sort of radar to DE's? This would give Dumbledore a strategic step 
up over Voldemort. I doubt LV would ever consider it, thinkinghimself 
omnipotant.

You have to remember, LV is at his core flawed, wanting to stomp out 
muggles and half-blood wizards despite being half-blood himself. 
While being a genius at planning (creating multi-level contingency 
plans) he is obsessive/compulsive with strong paranid tendencies. 
Still, his plans depend on the likes of Pettigrew, Malfoy, Crabbe, 
and Goyle. They obey out of fear or greed, but given the chance would 
betray to gain power.
