The Eldar have plenty of reasons to be arrogant, regardless of Slaanesh and the fall of the Eldar Empire. Like Callum said, humans were responsible for not only one Chaos God, but three, Nurgle, Khorne, and Tzeentch. Other than that, the Eldar have the most advanced technology other than the Necrons, Tyranids, or Old Ones, as well as greater intelligence than humans. Not to mention that the Eldar are way older than humans. Yet there is a difference between the Craftworld Eldar's arrogance, and the Dark Eldar's arrogance, the Craftworld Eldar are loosing their pride since they are now under attack by many, and have become weaker. The Dark Eldar are still as arrogant as ever, partly because they know they're practically unassailable in Commorragh.

By the way, it isn't a matter of how much each Chaos God has killed, they are equally evil no matter how old, or how many followers they have, each Chaos God is responsible for one horrible event or another.
