Where to start... where to start... Ah here, once I decided to go on a murdering rampage and struck a guy. So the guards and tried to arrest me, I resisted, and ran after the guy I attacked. After catching up to him the guard behind me attacked, not
me though! He attacked the man I assualted! Killing him right in the middle of the street!
Another time I was just walking though the Imperial city when I found that retired Mages Guild counsil member, and he attacked me! Just out of the blue summened a Frost Atronauch and charged! I backed up into the street to let the guards handle it, they did. But as soon as the mage fell dead they all turned onto one of the the guards!

Once he died, they turned onto another! WTF!
Now I may have mentioned this one before, if so then oh well deal with it.
I was walking around not really doing anything, when I saw these two Imperial Foresters shooting something, I walk over to their target to kill it... It was another Forester! So I walk back expecting to see a bear or something I maybe missed, nope. They were trying to kill each other. After the loner died they remaining two then turned upon each other! After one of them was dead I decided to experiment, upon seeing that the Forester left was hunting Deer and taking the meat I droped a piece of Venicen on the ground... Yup, he took it. Did he kill his friends over Venicen? Granted it it very good...
When I was taking Martin up to *Spoiler* I came across a couple of Imperial guards fighting each other (Like above ^), so I stayed out of it, but when one of them was left he then turned on Martin! To bad I did not realize Martin was an important character at the time... And that is the story of how I was invited into the Dark Brotherhood.
Beat those ^, I dare you.
