I'm confused, I dont remember seeing any Fred bitchiness, correct me if I'm wrong though
For me, Fred never really grabbed my attention. The relationship between her and Gunn struck me as a bit contrived and unlikely, and I put it down to the writers trying to make 2 fairly pedestrian characters more interesting (but not succeeding).
Now don't confuse my indifference to the characters as any reflection on the actors who played them, as I thought both Amy Acker and J August Richards did a great job with what they were given.
But the way I see it (and I accept not everyone will see it like this) is that Fred really wanted a hero who could live up to her ideals, even if she didn't live up to them herself. If they "˜failed' in any way, she let them know, and let them go.
For example, when she plotted revenge on the lecturer who sent her to a hell dimension (hooray, I thought, she has got claws! At last, a decent plot line for her"¦) Gunn steps in to save her from having the deed on her conscience and does the job for her. No matter how noble his intention was, however, she repays his consideration by turning a cold shoulder and rejecting him.
My dislike of Fred, really began though, during the episode in Season 3 when she visits Wesley after he has had his throat cut. It is bad enough that all his so-called friends at Angel investigations decide to stay away and pretend he doesn't exist anymore, but that's not enough for good ole Miss Perfect. She has to go round to put the verbal boot to make sure he's got the message, even though it's all ready apparent he's been deserted. Having barely survived both is throat cutting and Angel's attack on him, she then feels the need to personally deliver her own message of condemnation. Talk about kicking a man when he's down! See what I mean? What a bitch!
As for Fresley, I sincerely don't believe this was all it was cracked up to be. Not forgetting her penchant for judging her menfolk too harshly, don't forget she had had her memory altered when she decided she was attracted to Wes. Connor did not exist, nor did the back history of Wesley's so called betrayal at the time she fell for him due to the spell that Wolfram & Hart had cast for Angel. We will never know how they would have fared had she remembered what had transpired in the past. There was also a moment in the episode when Fred asks Wesley to help her plot her revenge against her lecturer when he asks why she didn't turn to Gunn for help. She replies that Gunn isn't like that (doesn't have a dark side), which is why she loves him. There is a significant pause when we are shown Wesley's reaction to this comment. The inference is that she has asked HIM because he HAS a dark side, and she will never love him for that reason.
As far as I am concerned I thought Lilah made a much more fitting partner for Wes. She understood the duality of human nature and didn't condemn him for not being perfect. Infact, I think the fact that Lilah was used by the partners to help lure Angel and Co over to Wolfram and Hart testifies to the influence that she subconsciously created around him. I think it was this strange liaison that was his eventual downfall.
Although I loved the episode AHITW I wasn't upset to see Fred go.
