Edge was the leader of The Judgement Day faction, before Finn Balor joined the faction. Rhea and Damian Priest wasn’t happy with then leader Edge, so they turned on him and made Finn Balor as the leader of the faction.
Finn Balor recently gave an interview to Daniel Cormier of ESPN, where he said that being a part of The Judgement has reignited his passion for the business(wrestling).
It’s reignited my passion for the business (being in Judgment Day). I don’t wanna say I was getting repetitive or stale but, I was getting very comfortable in the routine the I was in and I could go out there with my eyes closed and kind of perform and I felt fine, I felt comfortable and I don’t think that’s a good place to be. You wanna kind of push yourself and you wanna be excited to go out there and try something new and you know, I’d really wanted to dive into this heel character for a very long time and when I returned to NXT a couple years ago, that was the idea was, you know, to kind of to turn heel and start the character there and bring it back to Raw and SmackDown but in the timeframe of returning to NXT and turning heel, COVID happened and it took the live audience out of the equation so when you don’t have the live audience to play off, you can’t really be a genuine heel, especially someone who was notoriously a babyface his whole career. So it was very difficult for me to portray a heel with no audience to interact with so that’s where we got the ‘Prince’ tweener character where he was kind of a cool bad guy, kind of a cool good guy but somewhere in the middle. So I felt kind of robbed of that opportunity to play that heel character that I’d want to do and then, the time came that-that second run in NXT had came to an end, I came back to Raw and SmackDown, straight back to being babyface Finn and it was something that I was very comfortable doing but, I don’t like being comfortable, especially 22 years in. I want something new, I want something different, I wanna change and the opportunity came to turn heel and join Edge in The Judgment Day and that kind of all got flipped on its head in one night and we kicked Edge out… That was the day of because I was under the impression — the week before, I had kind of gotten a hint, ‘Hey, you’re going with The Judgment Day. You’re gonna be with Edge, Damian and Rhea’ and when I showed up on the day, they said, ‘Oh no, change of plan. Edge is out, you’re in.’(H/T: Post Wrestling)
