im sorry that this will be vague.
a possession movie where satan/lucifer possess a girl. she ‘tests’ people by tempting them with sin; on one occasion making a priest’s eyes bleed for succumbing to lust and kissing her. it ends with her leaving a police station, i think, and a voice over saying she is satan/lucifer and she is the test of mankind. something like that.
any help is appreciated
if I remember correctly I think its “the wicked within” from 2015.
