Market street the ugly and the good

For some odd reason I was walking down central market and I came across a situation that showed the ugly/evil and tremendous kindness.
Two women were at the wrong place and time and were punched/pepper sprayed during an altercation they were not involved with. The older woman was rather frail and not doing well with what happened. A guy who knew either women was helping them and pouring water in their eyes. I called the police and waved them over. Not sure how someone who punches/pepper sprays a frail older woman sleeps at night.
