Most humans are useless, egoism driven, grandma selling parasites.
They are good for nothing, go back on their words and without rules set by an elite they just abuse and kill each other. They talk stupid balderdash all day and are very stupid. They have sex with ugly people and watch pervertedly abhorrent sex movies. Also, they have fun watching other people suffer. I hardly can suffer their company longer than an hour a day and prefer to be with selected people or none.
Humans are discreet, selfish, and rather secretive mammals. They're complex, and one could think there is as much "bad" to them as there is "good." But, after considering that, one should also consider that all of the people you know and socialize with carry their own dark secrets, perversions, and histories. Remember, you only see what they want you to see. The person you hold in the highest esteem may very well be a sexual pervert within the shadowy sanctuary of his mind.
And is that wrong? It's human. People like to project an image of themselves to the world. Some achieve that image, while others never muster up the gumption to be so. Even then, what image doesn't have "darkness" hidden from your perception?
Useless? ...no, I wouldn't say that. Driven by ego? In most cases, sure. One must wonder why people think something as innate to humans as the "ego" is a bad thing. Good for nothing? At times for most of the population? Absolutely. Some people are lazy, unmotivated brutes who don't care about anything... neither themselves nor anyone else. It is common for humans to lie. Lying... flattery... they are social lubricants that move the cogs and the wheels of our society. Imagine, for a moment, what would happen in any singles bar if everyone started telling the stark truth? Why, the human population would likely tumble, wouldn't it?
As with all man-made, subjective terms, stupidity and ugliness are relative... as well as perversion.
Well, with all these selfish, morally suspect walking among us, it's no wonder it can drive one insane.
