Yeah, This is also the main problem with her. Lores of Brave Frontier tends to make her atrocities a bit offscreen. But her atrocities could be linked to the other characters quote and reaction and try to read this cutscene:

You can tell right now that this is the case of words speaks louder than action. Just look the interaction between Long and Xie'Jing. Also, She wanted to kill Fei & Fang after the interaction. Not only that, She has a trial based on that (Yeah, Brave Frontier has a content called trials) and it could be implied that Fei suicides himself maybe because of Xie'Jing sucks his soul:
