One of a few cases when "bitch" is completely justified. She endangered people's lives because of her greed.
Cue the protest of "political correctness", as if not explicitly deriding her gender would put us at risk of whitewashing her crimes. I've liked using the b-word too. I stopped after working construction in a rural town, where perfectly decent fellows would use the n-word in the same context as the b-word, e.g. That's -work, or: I got shotgun, you're sitting .
I found it hard to believe that I could use the b-word and not have it be a subconscious comment on what I thought of women. Holmes is an asshole, no thought of gender needed.
Double standards, must protect the m'ladies!
Also, you're probably aware that there's often different tolerances for in-group use of a word. That shouldn't be a surprise, really, it's usually not the physical presence of a word that people object to.
