I think most people would panic too tbh. Some would freeze (and therefore face the music by default rather than superiority of morals), some would take flight. It's human.
People talk with such confidence about how they would do x, y or z if they were in the shoes of somebody they think did something wrong but the truth is we rarely respond how we expect or pronounce in high stress situations. You don't know how you respond to a hypothetical situation until you actually experience it and it ceases to be hypothetical.
You see it all the time with women saying they wouldn't be raped like the victim in a news case because they wouldn't have gone there or would have fought or screamed or done whatever.
Except the most common threat response activated by the brain during a sexual assault is actually freeze. And you can't control your primitive threat responses when your brain perceives imminent danger to your life. Freeze, flight, fawn, fight.
In both scenarios all the confident "I would do x if it was me" are about people trying to make themselves feel better and safer, not reality.
