I still contest Future Lucy is evil. I don't know how or why anymore, she just is.

Also, as much as the writing can be bad in Fairy Tail, I do think they handled Future Lucy's death very well. Like, yha, Wendy could of healed her, but then Roguesting would attack her. Point is, Fairy Tail finally had a good death scene (that won't be revoked by shinanigans).

This death scene also benefitted from Lucy not saying "you aren't allowed to cry when I die" like Erza did in her pretend death scene.
