One does not need a PhD, a whole set of manual or even a book to understand 
and to explain to others the difference between good and bad behaviour. 
All you need is plain common sense... unless you are a little kid who has 
not been disciplined properly by his/her parent(s) or guardian(s) or unless 
you have some kind of a serious mental issue.

Not every single thing in this world needs to be explained with complicated
formulae, elaborate theories, scientific/historical proofs, etc... 
Just use your own God-given common sense.

I shy away from debates and so if one tries debating with me especially with
something as plain and simple as the above, he/she  will never get any response 
from me. I do not like debates. I do not like confrontations. This does not 
mean I am stupid nor am I a coward. No. This is just how I am. I will listen 
to what others say then state my opinion after... but only once... and then 
remain silent after. If I like the idea presented to me then I would definitely 
adjust mine accordingly.

I have always been passive and non-confrontational. I always let people be 
because I know that someday the bad things they have done in the past would 
haunt them someday.

When I was in high school, I was always on top of the class. A lot of students
in my class used to always cheat... even the guy and the girl (his girlfriend)
who ranked second and third in the whole school's top students were cheating.
Competition for the 1st spot was very competitive. I was even thinking that the guy who
used to be in the third spot all the time started dating the girl (who had
been consistently on the 2nd spot) in order to control her and take her spot...
in which he was actually very successful. The guy's main goal is to take my spot,
the 1st spot. I chose not to cheat. I chose to remain honest and I worked very 
hard to keep my place because I wanted to remain honest to myself and I 
wanted my accomplishment to be the true fruit of my own labour. Cheating is never in 
my list of acceptable behaviour... even the smallest incident of cheating.
Remember the "karma" I was talking about earlier? Well, going back to the story,
the guy and the girl never succeeded. That's because they cheated in school most
of the time. I never told any of our teachers that the rest of the class were
cheating because the truth would eventually come out someday. As always, I did 
not want any trouble/confrontations. I also had many good friends in the class and I
did not want to cause them trouble especially in our senior year. Heck, I even
made them copy my quiz/test answers and helped them with their school projects.
