Jaina doesn't believe Aethas because this is the second time his sun reavers have betrayed the Kirin Tor. We have a pretty good bet that he's innocent, Jaina and other lore characters don't have the benefit of our perspective as players. It's a harsh decision, maybe the wrong one, but I can definitely see why she does it.
