''Given the info that we know so far, Zelena has been seen to have done far less than Regina and Rumple. Can't say it isn't true. Hopefully, we'll learn more of her backstory in the upcoming episodes.''

Exactly. Zelena hasn't been on the show long enough for anyone to judge the extent of the evil she has caused. As far as I'm concerned, one doesn't need to commit a whole slew of crimes in order for me to consider their moral compass. If you've committed evil in any form - murder, theft, assault, kidnapping - then you've given in to evil in one form or another. Zelena has done it. So have other major characters on the show.
