Yeah Morgana does have her reasons for becoming evil and the ones to blame for her downfall were Merlin, Uther, Morgause, Mordred, Alvarr, Kilgharrah and Gaius. However I also blame Morgana herself because she partly allowed herself to be consumed with rage and hatred and she shouldn't have trusted Morgause, Alvarr and Mordred even though they had magic otherwise she wouldn't have been poisoned by Merlin in the first place and he still would have trusted her. Gaius and Kilgharrah should have allowed Merlin to help Morgana, especially Kilgharrah because Gaius just thought it was risky to help her inside Camelot but Kilgharrah believed the worst in Morgana and had no second thoughts or doubts about her becoming evil which encouraged Merlin to do the same. I don't think Arthur and Gwen were to blame as well for her downfall except by the fact that they distanced themselves a bit in Series 2 and Morgana just caused herself to hate them almost out of nowhere just because she didn't want them to rule Camelot but she had more reason to hate Arthur due to the fact that she thught he was no different to Uther while she was just jealous of Gwen.
