Easy yes. Corrupting children (Donnie) and heroes (Ethan Bennet and Harleen Quinzel, to name a few) alike is well beyond horrible even in coldblooded complete psychopaths' standards. His sick humor (so called comedic moments), from rigging the media for showing his lethal gas release as a form of sitcom to collpasing the city while imprisoning people in psauvdo-comical cells, highlights him as even worse. And there's the part where he impersonated Batman for gassing people under the law's protection while attempting to turn the true Batman into another Joker.
