I agreed with removing character introductions though, so I imagine leaving that as is…
I prefer keeping Cassian more heroic and having an implied character fault. Having him kill the informant, who lost likely has an inconsequential role, in cold blood and then struggle to kill a scientist responsible for weapons development for the empire doesn’t make sense to me. If simply having Jynn there makes him second guess, that makes his conviction and allegiance shakey at best. Not seeing him do dark deeds helps the narrative of struggling to kill.
