Did Maul really fail though?
Ezra had already activated the thing, and he wasn't going to get up there without running into Vader
His only goal was to ESCAPE FROM THE PLANET and he did that. Took the first chance he could to bounce, after planting the proper seeds in Ezra lewd
Maul didn't even get hurt, and he made out like a bandit. I fail to see how he lost. Kanan tossed him off a ledge big whoop, he wanted to leave Malachor that was his entire goal.
