Watching this episode made me think, isn't Erza taking too much blame on herself for Simon's death. In the end, Simon's death all boils down to Simon's personal decision to cover for Erza (and Natsu) and Jellal for actually using an attack that can kill (while taking into account serious brainwashing).

Plus if we based on what Erza said about her "weakness" killing Simon, then she might as well say Simon's death is Natsu's fault too since Natsu was getting beaten up by Jellal and angered Jellal into using Altairis thus requiring Erza to cover for him.
