My brother justified it to me as "name a jedi that was able to look at an innocent dying and then do something else." I guess it also helps that those holocrons could possibly save millions with nothing concrete, and since we didn't know first hand what was in them, we can't be sure they would have cures for anything. The woman in the fire died, and that was definite. Either way, my character let her die to save more, and doesn't lose any sleep over it.
