I don't agree with it, but from the Russian's point of view, the Terrorists were the bad guys, they decided to do the kidnapping, the Spetsnaz had a mission to achieve, they achieved the mission.
I would think the Russians believe in live by the Sword, die by the Sword and the terrorists brought it upon themselves.
The added bonus for the Russian's was that they didn't have any more kidnappings in the future.
