Law

I study Business Management, but im that person that questions everything, a lot of people could call me a pain in the ass, but i think of myself as a person that wants to know every small detail.
Couple of my friends are in school to be big shot lawyers and i wanted to know why.
I started asking questions that couldnt been answered as such, do you believe in death penalty (when the person prosecuted just killed your family)? I got vague answers as, if they are proven to be guilty they must be condemened to a required sentence.. but i could see in there eyes that ancient roman law eye for eye was the only thing that could make a diference (death).
Then i started to hit the weakest point a lawyer could have, are you really helpfull in this case or are you just someone that sees an opportunity and tries to suck every dime out of it?
I sincerely think that MOST of lawyers try to get through life defending everything they can, rapists, thiefs, murderers.. I mean how does someone defend a person who just raped a child??
When i said this in a room full of lawyers (just to get people pissed off) they started to curse and screaming at me, i felt kind of happy cause i knew that it was the only way to get a straight answer.. They said that common people couldnt be in charge of a democratic system, i asked why?
After a couple of minutes till they had an answer that made any sense, their words were this.. "if i study four to six years to learn how the system works, i can know how to exactly turn it to my side"
I got a honest answer, and i know that 95% of lawyers out there feel the same way.. Shit if our justice system doesnt work what the fuck do we have to count on?? Personal revenge?? mercenaries?? Some people just dont deserve to live..
