the safety of ourselves and others are both very simliar although they say put urself before others so that way u can live long enough to help the other person. but our safety is related to others cuz we are all humans and wut we do affects others. in a good way or a bad way it affects everyone depending on wut it is, for example the things police officers do r to protect ppl around them, sometimes they dont make the best dessicions (killing black ppl just cuz of their olor or for no good reason) and sometimes they get scared so they end up hurting someone cuz of a fake gun or soemthing but sometime they dont realise how that may affect the ppl around them (mainly that persons family) and it also affects the way ppl veiw police officers cuz it makes ppl fear them.
thats a good way to veiw how something ppl do can affect others. we must make sue we are safe and also that other ppl around us r safe cuz we are all important
