Honestly Zelena DID want to be good and was definitely trying. It was difficult for her because in 3.16, she found out all at one time she was not wanted (By her biological mother and her adoptive father), wasn't really her adoptive father's daughter, and was called wicked by her adoptive father. That could be the biggest reason why she chose to change her past, is to avoid that.

The other big reason is because Glinda wasn't necessarily the most trustworthy or encouraging figure. She was okay with Zelena turning the Wizard into a flying monkey. That was very shifty of her. She also knew about the time travel spell, but didn't say anything.(Even with trying to direct Zelena down a different path, she should have let her know and then redirect her) She also did a very terrible job of keeping the book of records safe and hidden. When Zelena found out that Glinda wasn't telling her everything about the prophecy, it created a divide between them.

The last big reason is Zelena's belief in the prophecy. She heavily believed that she was going to be the greatest evil, because her father called her wicked, and because Dorothy arrived in Oz by cyclone. Glinda should've pointed out that Dorothy didn't have any magic, but didn't. Zelena accepted the prophecy and then became the Wicked Witch of the West.
