The burly man hurriedly pleaded for mercy, "Spare me, hero!"
You originally intended just to teach these people a lesson, killing them was out of the question since these guys aren't terrorists, anti-government militants, nor drug lords; they're just some bullies taking advantage of others.
Upon hearing the burly man's plea for mercy, you tossed him aside like trash next to the garbage can, with a steely expression and a cold face saying, "Scram!"
Several uninjured individuals hurried forward to support the burly man, dragging their remaining companions to make a quick getaway.
Once these people left, the onlookers quickly dispersed without any applause or cheers as seen on TV; passersby were merely spectators, watching was enough and the rest had little to do with them.
