Since we are not explicitly talking about this in terms of Epicurean philosophy,
We're going to have to figure out some way of clarifying that. It's like with "Gods" -- the definition is so different in Epicurus vs the non-Epicurean traditions that the words mean dramatically different things. In analogy to Epicurus saying that supernatural gods don't exist, but "real ones" do, we've got a situation where we (and probably Epicurus) refer to "evil" all the time, but do not mean anywhere near the same thing as does society at large. In Epicurean terms I would say there is no such thing as "absolute evil" (other than perhaps "pain" in a generic sense) just as there are no supernatural gods.
Unless we keep this clear the conversations are going to be hopelessly confused.
If anyone wishes to argue or imply that there is such a thing as "absolute evil" (in all circumstances; all times, all places, to all people) it would probably be good for them to state that explicitly so it can be fleshed out.
