The only thing that was made worse is that Cassandra felt like an idiot afterwards, and thought she was unworthy to even be in the Inquisition. Justinia herself is the one who sent Cass.. she would have protected Hawke.
But all like most dwarves, everything is just cute or a joke to you (or characters like Varric). Always the rodeo clowns of fantasy.
Hey now. We don't know what she could have done. She wouldn't be able to take on the whole world that blamed Hawke for the war. She feels like she doesn't belong because she couldn't stop the rebellion from happening. She knew that it was bad, but did nothing to prevent it from getting worse, not because she couldn't find Hawke.
What? Cute? A joke? I don't see how anything I said led you to that observation, but ok.
