As a species, we don’t really need “evil” anymore.
It’s hard to have empathy with the broad stroke of “evil.” Maybe as a de-generalising force, it seems contradictory to the above quote, but empathy is also a trait that allows the creation of better, more finely-tuned simulations/stories. And better simulations mean better chances of preventing things like this from happening again, rather than painting the bombers as fundamentally “bad,” no matter how tempting that might be.
As a species, we don’t really need “evil” anymore. That is, we can do better. We have evolved past it. We evolve better without it.
