I don't blame you. As someone who read the original LN, I can honestly say that it gave more reason to Atalanta's actions. They revealed that Atalanta was disgusted with Jack and Reika for involving children (in the LN, she brought a horde of living children to serve as hostages to restrict Jeanne and Sieg's movements and kill them, kinda like what Caster Gilles did with Artoria in Zero).

The LN also shows that the encounter with Jack resulted in Atalanta's arm being imbued with Jack's evil spirits, which were slowly driving her insane and telling Atalanta to avenge them (Jack) by killing Jeanne. While Atalanta is powerful enough to exorcise them on her own, she kept it because she saw her inability to save Jack as a sin.

I do believe that the anime could have gone a bit more into her character - even I was pretty confused, saying "When did this happen? Atalanta, what are you doing? That makes no sense!" - but regardless you are entitled to your own opinion.
