I didn't have the pleasure of the original run, but I read the Avengers/Tbolts mini where she seemed to have a hysterical breakdown from the pressure and not being with Hawkeye enough. For someone reputed to be a cold manipulater, she goes emotionally haywire a lot and gets super violent. But she's also made multiple efforts at redemption...I remember when she was first broken out of prison, she insisted she'd wanted to serve her time and be free legally.
