My theory

The fact that you are not upsating anybody gives you the feeling you're not doing something wrong. If I do something that makes people feel good and I feel good about it too than it's a good thing.

Men are program to be born on this world carnivorous..... that's the reason why there is a set of rules to follow just to make a human more civilized and to do good things: Bible, Koran, FungSui, Law, Golden Rules, Sayings, etc..... they are all made just for us humans to think several times before committing any sins.....

You said "Right or wrong, it really depend on what you think". I just want to add "right or wrong, it really depends on what you are trained to think", because every society has different points of view about what characteristics form the good or bad persons.

K i dont really get your comment because their are bad and good people out there and you cant really say that there is no wrong or right because then your kinda saying that you dont know the difference. if you dont know the difference between right and wrong or good or bad then thats a psycological problem. ppeople who murder and hurt people go to trial and if they cant tell the difference between right and wrong then its considered that somehting is "wrong" with them and they way they think. dont take my comment as rude or debating. I am just simply stating that it doesnt work for me or make sence to me. believe what you want to believe. and great discussion it defiinitly get s you thinking and makes people want to answer.
