My understanding, please correct me if wrong, is that the Baha'i perspective on evil is similar to the Catholic one I outlined earlier, at least according to Abdu'l-Baha in Some Answered Questions:
Briefly, the intellectual realities, such as all the qualities and admirable perfections of man, are purely good, and exist. Evil is simply their nonexistence. So ignorance is the want of knowledge; error is the want of guidance; forgetfulness is the want of memory; stupidity is the want of good sense. All these things have no real existence.
In the same way, the sensible realities are absolutely good, and evil is due to their nonexistence—that is to say, blindness is the want of sight, deafness is the want of hearing, poverty is the want of wealth, illness is the want of health, death is the want of life, and weakness is the want of strength.
This is very close to St. Augustine's description of the non-existence of evil in the fourth century, as a privatio boni (absence of good):

So, I think Baha'is don't believe evil exists either in any real, metaphysical sense.
What is the Jewish and Islamic position, I wonder? I've never directly studied that issue in their theologies in isolation, so I can't quite recall off the top of my head.
Viewing evil as the absence of good, as darkness is the absence of light is perhaps the most useful statement that can be made as to the question of evil. However Shoghi Effendi has also said evil exists.
We know absence of light is darkness, but no one would assert darkness was not a fact. It exists even though it is only the absence of something else. So evil exists too, and we cannot close our eyes to it, even though it is a negative existence. We must seek to supplant it by good,

I had not realised the Catholic position was so similar to the Baha’is. For me personally, that’s another big tick for Catholicism.
I imagine there is huge diversity as to how Jews, Muslims and Christians view evil and perhaps the most relevant factor is the extent to which sacred writings are viewed literally or metaphorically.
