Could Jesus Christ actully redeem the people who live in Hazbin Hotel

So the MC of this story isn’t really doing the best job of redeeming people and changing them for the better. I was rather disappointed by the lack of positive character development. Also angels aren’t good and the demons are not either. These facts not withstanding how well could my main man JC go about redeeming everyone.

He is all about grace and mercy and is omniscient. Which characters actully could get redeems or have enough good inside of them to be redeemed. Amy way you slice it with how fucked it is over there Christianity should be a big hit. “Come Azazel walk with me”
