*SIGH* im going to try again...
evil is a perception, it is not real. you can percieve what a person does to you as evil, but it is only evil to you; and others who share that opinion.
EVIL IS AN OPINION.
GOOD IS AN OPINION.
O P I N I O N S _ A R E _ N O T _ F A C T S
even if only ONE human being on earth has an opinion, and EVERY OTHER HUMAN has the exact opposite opinion, that one person is no wrong.
not to say everyone else is either, but the point is, good and evil are opinions, you cant have mob rule determine what is good and evil, only you, yourself can determine what is good or evil, BUT- you cant do anything about it without imposing on other people's wills. free will is a gift from god according to religion, so therefore if you impose on someone's will, you are sinning.
EVEN IF THEY ARE IMPOSING ON SOMEONE ELSE'S WILL, if you fight fire with fire, you'll only spread the flames.
this is why law enforcement is a sin.
this is why the world is a cespool of evil.
