Of Confidence, Over confidence and... Insanity

If I feel that people are not talking to me, that many people from my family or people from my workplace don't seem to like me, my first and foremost thought would be "what am I doing wrong?".

Now, here is a "man". He hates his whole family. His brothers, sisters-in-law, his nieces, their husbands, and even their infant kids(read 1 year old) have a list of "wrong doings", bad behavior and ego hassles (with him) in his books. According to him, they all like each other and always call each other and plot and plan against him and keep him out of all discussions.(!!!) According to him they are all walking around with egos and inferiority complex because he is this super-awesome successful (Hahahahaha) man. (Is there some scientific name for a mental condition of inflated self importance of this extent?). In a nutshell, everyone else in this world, his complete family, everyone he works with/deals with don't like him because (and hold your breath for this one)...THEY are all bad people with complexes and problems, who are beneath him and don't know how to behave and only he and his wife and kid are the awesome ones. And the worst bit? The sub-standard, street-worthy language he uses with his family or while bitching about them to whoever listens.I wonder how people of such high class and standards use such words so readily. Guess they must have learned them specially for communicating with/about the rest of his (bad) family who are beneath him.

And then, as they say, behind every super awesome successful man, there is a woman, he is also blessed with the supporting kind. So, when he screams and abuses at his elder brother, used to talk shit (literally) about his father and mother and treats his younger brother and family like completely beneath his attention, his wife sits by his side and smirks. And, if any of us (very adult) kids have had enough of this bad behavior, his sub-slimy, sub-standard, cheap, bad mouthing, and finally say something in response, the madam grandiosely walks in and say "please talk to my husband in accordance to your age." (I wonder if she has noticed that her husband is younger to his parents and elder brother)

I mean, they actually keep their neighbor brother's post with them and find it beneath themselves to give it or even let them know that these letters exist. The brother is supposed to just go there from time to time and beg for those in just the right words and tone! Can you beat that shit?

Now friends, especially of the doctors of the mind variety, please enlighten me as to what could be the cause of this supreme and total self confidence that prevents any doubt whatsoever that there might be some issue with self, when one cannot get along with the rest of the  world. This supreme belief, that  no matter whoever hates me, it is always always someone else's fault, and I am always better than the rest.  Because, if this is a mental illness we all could find it in our hearts to not hate and detest this man and wife and treat them with some sympathy instead. 


And instead, if it is something else, then too much of it is bad of course, as you can see from the symptoms above, but I'd like a little, teensy-weensy bit of what he smokes to take care of any self -doubt and confidence related issues in life.
