At their absolute wickedest, I believe Regina took the cake. As for evil spread out over time, it's hard to say. If we voted though, I'd say Regina was worse. She murdered her father, whom she actually loved more than anything, just to hurt others, including those completely unrelated to her own petty little war with Snow White.

I always felt Zelena was more bark than bite. Sure, she was wicked, but she was like Eskaver said, not as likely to kill indiscriminately. She possibly could have killed the Good Witches (maybe that was beyond her or maybe she still held them dear in some way) and she also sent Dorothy home with her most powerful possession (the Silver Shoes). Whether that was because she was actually afraid of Dorothy's potential or she was getting an innocent child out of the way, I don't know.

Regina even killed people during her musical sequence, while Zelena just scared the populace (and gave them an entertaining song.) :)
