Yeah, if everyone in the Gotei 13 knew about her violent past, it's no wonder they were all terrified. Even Squad 11 members, shown with the 2 guys in treatment who complained about the food they got, when she approached them and told them their lives were in Squad 4's hands.

And her violent past self is definitely the reason Kenpachi Zaraki looked up to her, she was the first person he fought who made him feel fear. And probably the first who ever injured him.
