Psychology of the criminal

Psychology of a criminal is a psychology that generates a number of justifications for all the illegal actions people perform. It is a psychology different of the one other people have. As talking about "other people" we are talking about those who strictly follow rules of morality and legislative rules of society. So, it is obvious that psychology of a criminal is a perfect polarity for psychology of other people. The question is which the main differences between those psychologies are.
Criminals are people who sharply percepts even the tiniest unfairness of this world. They percept it sharper than other people, as one faces the unfairness there are several kinds of responses for that unfairness. People can forget about it in case if the unfairness has nothing to do with them, or they may try to do something in order to make things better. As a result revolutions and strikes appear in the society. Those are people of a character and they are able to do something.
Though criminals act in the way different from the way other people act. They are rather selfish people in some way, or they are people of lack of self-confidence. One way or another they will never do some global actions, they will do things that will make their life better. They express their protest against social or political order on their illegal actions. They do realize that those actions change nothing, though they have certain changes in their lives and it is enough of changes for them.
