Nothing like hours of time and a well read report, as usual the pilots had much less time and much less info to judge the situation. Other than a structural failure fire is probably the worst situation you can have. Ecam message of fire would defiantly get me thinking about getting power off and getting it on the ground ASAP. Just think what the discussion would be if they had waited until they saw or smelled smoke, disregarding the ecam, crashed and killed everybody.
