For what it's worth, don't do this, you also know you need to give people space and in hindsight, because of what happened, you only now think should've done something but I'm sure there were wholesome reasons why you avoided intervening in the first place. Just as easily they didn't make the attempt and you would've thought you made the right call. It's not on you.
