I think it's that neither Frisk nor the monsters are expecting to encounter each other, and they get scared and start the fight. Most monsters believe that humans are strong and dangerous creatures and they probably want to protect their loved ones from the "dangerous human." However, if you don't attack them, you show that monster that you aren't a threat, and then you can spare them. (Note that once you "clear" an area, the monsters stop spawning, i.e approaching you to fight) Alternatively, you can attack them to show them just how powerful you are, and they stop wanting to fight you. Most of the time, it takes at least TWO attacks to kill a monster, so the first hit(s) just sends the message "leave me alone," but that last hit is what turns you into a killer.
