[Batman Begins] Bruce has problems killing prisoner yet massacres whole League of Shadows with no problems at all?

How is it different to kill them but not the prisoner who was a murderer?

It's sketchy, but he didn't kill any of them directly. Even the fake Ra's al-Ghul was killed by a falling roof when he went to finish Bruce off.

The rest of them - they're trained ninjas with fully-functional common sense. They should have been able to clear out of a burning building without difficulty.

The real problem is the prisoner he refused to kill, who was then stuck in a burning building with no ninja training and no knowledge of where the exit was.
