Well we know Vergil is very much alive by the point of Limbus, so I don't think he'd die. Maybe.
Philip was a different case, using the tightrope metaphor he was still balancing on it during Wedge only to fall off and Distort when Oswald broke him into TCC. Xiao made it to the end of the rope and got EGO, Yan spedrun jumping into the abyss of Distortion. Roland was a really weird case considering the Library was at the height of its power, it was likely closer to how Xiao, Philip, Yan, and Tomerry overrode the stuff of the floors we used.
I don't really like agreeing with Mimi, but she does have a point in the QNA regarding Catt Distorting back that it's harder to forgive yourself and fully spring back into a strong resolve, as opposed to having a strong resolve yet breaking when something pushes you past your limit.
Stando Dante would be fucking hilarious and if PM goes that route I'm all onboard for Limbus.
