It seems like she was damned from the start

I agree with the others about her not taking responsibility for anything she's done. This speech is especially self-pitying in her wish to be removed from everyone. Her desire to be separated from everyone else began earlier in the play when De Flores suggested that she only ally herself to him and forsakes her family. Now she has continued his sentiment and hopes that she be discarded from her family, which is further emphasized through her mention of being physically removed, as though she were an ailment, from her father's blood. She seems to suggest that her corruption was not her fault but that she was destined for it and yet she allows for her corruption to have stemmed from her hatred for De Flores. In the end she seems willing to take minimal amount of blame by either suggesting that she was always doomed or that it stemmed from her early hatred. She does, however, admit that she is entirely wicked now.

Realization of the Stereotype

I agree more with Christina. I don't feel like the passage is so much a passing of the blame as it is an explanation or recounting of events unaware to Alsemero. While Beatrice seems to take an apologetic tone, it think she is more regretful that things couldn't be different. As she says many times over though, she is fated to be a corrupting source. I find it ironic that in all the plays we have read, women have often been the source of conflict whether through their own means or indirectly, and Beatrice is the only one that seems to recognize the plight of her own sex with the stereotype of women presented in Renaissance dramas. In the end, I see Beatrice's little monologue as a regretful explanation in which she demeans herself perhaps to make sense of what she has done to Alsemero.

The Fall

I don’t think Beatrice is necessarily shifting her blame onto others. Instead, I think she, like her father, is surprised at her behavior and its implications and is just trying to figure out how she fell so far. When a list of her actions were forced out of her by Alsemero, she realized that she had lost herself and tried to find an answer for how much she had changed. Finally coming to none, all she can offer are excuses. “I know that I’ve become an evil person but I still don’t know how I got this far. Maybe it was fate, or maybe it was always my nature but it just didn’t surface until now. Either way, my shame and sins can no longer be brooked and thus my fate is fitting.”

Beatrice and Akon Should Have a Talk

I agree that Beatrice isn't really taking any blame on herself. Though she is demeaning herself and saying she's just her father's bad blood, she isn't really taking any responsibility. Instead, she's just saying that she could not help what she did because of her nature. She's even blaming fate, rather than take any responsibilty:

"Beneath the stars, upon yon meteor
Ever hung my fate, 'mongst things corruptible;
I ne'er could pluck it from him"(5).

Here she makes her actions seem an inevitable course of nature. Though Beatrice is now found out, she does not redeem herself in the audience's eyes by repenting at all.And just because I'm listening to this song right now, I think Beatrice should have sung Akon's "Blame on Me":

"I’m sorry your life turned out this way
I’m sorry that the FEDS came and took me away
You can put the blame on me
Said you can put the blame on me".

A Warped Apology

When I first started reading this passage I thought it was going to be Beatrice apologizing for what she had done, because lets not forget she is the one who started all this to begin with. But instead, she begins to blame everyone else but herself. I mean she is the one who made the choice to employ De Flores to kill Alonzo. But here in this passage, she starts off by saying she has bad blood; the blood that would have been drained from her father if he had gone and seen the barber. And then she goes on to say that she also could not have helped what happened because of De Flores, and that she was tied to him because of her hatred for him. Not once does she say, you know what I'm partly to blame for what has happened, but instead she tries to blame it on other factors, specifically ones she cannot control like blood and the meteors.
