[何を信じて生きればって] ≈ ["何を信じて生きれば"って]: this phrase functions as an adverb modifying the action afterwards: [with the thought "what should I believe in"...]

[まま] is not so much [still] as [remaining in the state in], IMO.

Also you're entirely missing the end of the the second line [朝を迎えていた], which is inseparable from [まま].
