Is it possible to go in the wrong direction when you are certain you are right?

I'm thinking of doing a weekly installment of this thing, so that I will remember to keep it updated. Since the book is now complete and revisions are underway, I can focus on other things now. Dealing with life in general has left me a little winded lately, and a few of the traits in humanity that completely irk me have left me confounded how such folks are even given the chance to right themselves.

There are several things in this life that piss me off, among them is the fact that people will take advantage of others. Some indirectly, some directly. Either way, whenever it happens - you try to tell the person what they are doing is wrong, correct? But what if you have that one that will not listen for whatever reason? Be it ego, drilled in their ways, or just simply convinced that they are not, no matter how much the evidence piles against them? Either way, we know that as humans, manipulating and taking advantage of others downfalls is evil and wrong. These types of people are the ones who, when you try to convince them of their error, will tell you that they are not doing such things and will scoff when you confront them about it.

Is it then, when you realize just how much humanity is doomed?

Add in that these same folks will then try to justify their positions with nothing more than false statements and their convictions that they are right, and you have a situation where people are just hopelessly lost in their own ways, and there is no way to stop any of it. These are the same people who will come into your home and take over the place like its theirs - establishing rules that the household will follow because they said so. You know this is wrong, and most normal humans will stand up and tell said person to get out, and only to come back when they realize their error.

Is it then, when you realize just how much humanity is doomed?

These people have no respect for you, but demand it at all times from everyone around them.
They will take over functions that are not theirs.
They will claim that everything they can do cannot be done any better.
They will claim the victim everytime something is turned on them.
They will say that they are never in the wrong for anything, and accuse you of being the one who is in the wrong?

Even if you are right and everyone around you, except them, knows it.

Adieu.
