In the end it's Death Devil giving a sales pitch to save her own ass, which most people predicted was her objective (rather than being erased).
She's the most untrustworthy narrator in the history of the series so I wouldn't take everything for granted from her.
What she's saying is probably partly true but she's lying or exaggerating about some things and omitting certain facts.
Miri showing up doesn't help her case either as he's the most gullible character in the entire CSM. This isn't like Kishibe showing up to back her up.
