We are all going head to head in being douches. Not a big difference between us. One day we are nice and give stuff for free, so the other day we can murder, rob, steal and troll. Difference is some people just wont ever admit, that they are douches. I know. I'm a douche bag. 
One of the ways to identify the bag-guys is...they often try to make statements about themselves that are conveniently wrapped inside a big fat "Everyone Does It" burrito. Speak for yourself.
No, we are not all going to act badly. Some of us, albeit only the suggested 10% or less, will not act any worse in this game than we do in RL. It depends on your play style as many other threads have pointed out.
So i'd like to name a few guys who are so bad i am nearly speechless:
Wind_Drift - avoids all real PvP combat and prefers to snipe level 1 miners. Not honorable at all.
Donkey - avoids all real PvP combat. Wind-Drift's apparent "superior" who could not stand still and talk with people at NCR last year - no, he had to shoot unarmed people there over and over [and over and over].
These are two of the most hateful people i ever met in this game. Both members of
Section Hate.
To Wind_Drift's credit, i will point out that when he led a S8 raid on a GN13 base last year, i do believe him when he says he made his team submit to a forced inspection on exit, to make sure they didn't steal anything from GN13. Sometimes the bad guys know what they would do if they were good guys, and thus we'll see honorable actions from dishonorable men.
Maybe this year S8 will try some PvP? And don't point to the Modoc video where WD is there - he used the Grim's as a security blanket to claim he "did some PvP" lol.
