Adalind went after Juliette in retrobution for Sean abandoning her in his pursuit of control of a grimm and she did it again later to try and force the gang to reveal Kelly's whereabouts, otherwise Juliette on her own was not the cause/reason for Adalind's actions. She was nothing more that a tool. If you took Juliette out of the equation by her leaving Nick and moving away, Adalind would have had no reason to go after her on either occassion  because it would not get her what she wanted, payback against Nick and Sean and later a reunion with Diana. If Nick started dating some other random woman, I'm sure villain Adalind would have acted the same towards her because her real target was always to hurt Nick by hurting the person he was dating. The Adalind of S5 & S6 is not like the first so her actions, wants and motivations are vastly different.

Both Juliette and Adalind acted horribly at some stage of their lives for whatever reason we saw in the end, they both got themselves together and moved in a positive direction. They may not have started in the same place, Juliette as the good girlfriend of the protagonist of the show that suddenly went bad and Adalind as the antagonist who decided she wanted something good for herself. One can't let only the past actions define the character as they are in the present.
