Chris and anger
Chris has anger management issues. This usually surfaces when he is under stress.
Causes of Chris's anger
Chris' issues with anger may stem from being tormented in his early childhood by his abusive babysitter whom he was frequently left under the care of while Bob and Barb would go out clubbin' and takin' shots. She allegedly traumatised Chris by locking him alone up in a room full of toys when he was a year old. How ironic. Roach also possibly performed other disgusting acts upon 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.
Another cause of Chris's anger is the fact that as of the time of writing, Chris is still a virgin. Being a virgin seems to make Chris feel like he is entitled to being allowed frequent moments of rage and seeing as he only manages to jack off twice a week, due to his bent duck he has large amounts of testostorone stored up in his body he just has to get out.
Examples of Chris's anger
The way Chris expresses his anger can be considered confusing to say the least, in one of his early fits of rage he began to shout Curse-ye-ha-me-ha at several jerkops who were trying to kick him out of a local Walmarts. Most normal people do not shout anime references at people who are making you angry.
Chris also expresses anger in the same way a six year old does, taking out his anger on a video camera seeing as he knows it obviously can't and won't fight back. This can be seen in one of his videos on Clyde Cash where he seems to be "Hulking up".
A great example of Chris's anger can be seen in one of Chris's most imfamous videos, his "Youtube Finale". 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.
