If you fell in the water and was drowning
you would need a person to save
you. Doctors cure your diseases and dentist
fix your teeth. Wanting to hurt people for no reason, you mention, is not fare to other human beings. Youve become a judge and jury and we have seen through history what these type of people can do.
As far as some people saying ignorant things and wanting to hurt them, im sure you have said ignorant things and would not want someone to hurt you because of that.
