(Sorry, wonky formatting) I respect your opinion, but that's not what I got at all from her character. Yes, she was headstrong and had a lot of underlying anger. I never felt she was bullying someone (which means misuse of power over weaker persons).
Partly, yes. The actress played it as having PTSD.
That said, I thought a lot of her anger was pretty justified.
Quark (who certainly wasn't weaker than her) did a lot of shady things, some of which he should hav gone to jail for. So she didn't like that, or him. *shrugs*
She has her reasons, obviously, but she's angry at:
- Dukat. Ok, Dukat is a terrible person (quite frankly, he's a monster) and completely deserves it.
- Quark. Ok, he's a crook.
- The provisional government. Ok, the provisional government is incompetent and corrupt to some extent... or, at least, she perceives it that way. Whilst being part of the administration (as liaison officer to DS9).
- The Federation. Ok, she perceives the Federation as new invaders.
- Sisko, before learning he's space jeebus. Ok, he represents the Federation.
- The station computers.
- I forget who else. Long time I haven't seen DS9 (at least in its entirety). It just seems that in every scene she's angry and yelling. I found it grating.
Sure, she has her reasons (some very valid, some less so), but she always throws a tantrum whenever something doesn't go her way. IRL, people like that, you always feel like you have to walk on eggshells around and it's exhausting.
(aside: Quark absolutely is weaker than her. She's second in command of the station, he has no authority. Physically, she could very easily overpower him.)
