I see it being similar to this ^ for most anyone, Lili included. There'd be a lot she could tolerate for the sake of the people and making them happy and fulfilled but if it came to the safety of Eorzea? Nope. Not messing with it no matter how exhausted or annoyed she might have been with people prior.
She'd think of the abilities as more of a sign from Mama Crystal and the Twelve that she was meant to put such abilities to work for the good of others. That's what I imagine, anyways. Keeping it from turning into a TLDR because there's just soooo many facets to the Warrior of Light people don't think about.
