I agree. Carol isn't Bendis's mouthpiece here, she's angry, hurting and looking for someone to blame.
The fact that Janet (I think) points out immediately that Wanda would forgive Carol under the same circumstances pretty much sealed it for me that Bendis wasn't condemning Wanda, in any way. They're all sympathetic characters, here.
He demonstrated it again in New Avengers #26, where Clint was all torn up about Wanda killing him twice, and wanted answers, and possibly revenge. After he realised he would get no answers (and after the oddly OOC sexy time), he just left, eventually telling the New Avengers that what he found would do no one any good.
