Eh, technically the DC Showcase shorts don't have much connection to the comics and are mostly isolated tales that are simply designed to...well, showcase specific characters--and may or may not be set within the same universe or any known continuity for that matter. And even if we know for sure they're all set in the same universe, Lorraine (as far as my research has proven) has the highest bodycount of any villain there.
