As a christian, I'll definately help if I don't pose a danger to
other pple by stopping by. You never know... This person might need
more help other than the 2 guys who stopped by. Maybe can call
ambulance for them, apply first aid, prevent the casualty from
going hysterica from his blood... many things.
A good samaritan will accompany the victim to the hospital, then
pay for his bills and help him contact his family and tend to all
the immediate needs (at least) before leaving. Then go back and
settle your work. I'm sure God will help your boss or friends to
understand. Put yourself in the casualty's shoes. if you were to
end up like that, and someone do all these for you, will you feel
touched?
