Chris and anger
Chris has anger management issues. This usually surfaces when he is under stress.
The stem of Chris's issues may have began after being tormented by his abusive babysitter who would lock him up in a closet as a child and possibly perform other disgusting acts to him.
Another person who may be behind Chris's anger issues could be his father Bob Chandler. Being Bob's son, Chris would likely be afraid to retaliate to the things Bob does that annoy him such as very rarely washing his hands and occassionally cutting down the internet. Chris then takes out his anger on innocent well-meaning trolls such as Clyde Cash.
A great example of Chris's anger can be seen in one of Chris's most imfamous videos, I'll strangle that Clyde Cash. In this video Chris repeatedly threatens poor Clyde, claiming he will indeed strangle him some day even going as far as telling Clyde he will even comit this henious and reprehensible act in a police station, showing Chris has no control over his angry feelings. The fact Clyde was only trolling Chris in an attempt to lash out at him for his role in the death of his late brother Ryan Cash shows even further how much Chris may require a couple of anger management classes.
There's also evidence he killed Clyde Cash in anger. http://www.youtube.com/watch?v=FiTVga0G8Ws And while the video is good evidence, it may not be accurate because Chris had only shotgun shells and yet killed Clyde with the BFG9000, which uses plasma cells. Other than that, it's proof positive of the murder.
