Ah, I think this is where we come to the parting of the ways <g>

"the person Sirius cared most about in the world was you [...] you 
were coming to regard Sirius as a mixture of father and brother. 
Voldemort knew already, of course, that Sirius was in the Order, 
that you knew where he was -- but Kreacher's information made 
him realize that the one person whom you would go to any 
lengths to rescue was Sirius Black." -- OOP 37

Sirius could not possibly endanger only himself. Any danger to 
him was a danger to Harry, a danger that Dumbledore could not 
protect against, because in Harry reposes a power "more 
wonderful and terrible than death, than human intelligence, than 
the forces of nature [...the power that ]  took you to save Sirius 
tonight."  Dumbledore knew that if Sirius were captured Harry 
would go after him and he would *not* be able to prevent it, any 
more than he had been able to stop Harry from going after the 
Stone, or entering the Chamber, or following Ron  into the 
Shrieking Shack.

Sirius was more heroic than we realize. By keeping himself safe, 
much as he hated doing it, he protected Harry until Harry had 
strength enough to survive the confrontation with Voldemort at 
the MoM.
