He could’ve called cops and went about his day(if he want to be a hero). No need to intervene on that situation. I remember a little kid tried to get my cousin (my cousin was 17 at the time) to go in her house and help her mother with a domestic violence situation. He pulled away and was like aint no way I’m walking in your house. Her mom got her ass beat and she stayed with that man for a few years. We routinely would hear them next door. Sad situation but there zero that could be done because she wanted to stay.
