Crime, in most cases, is a one-way street. It's like a marsh: if you land on it, you will only sink into it; there's little chance of your coming out of it.
Similarly, once you commit a crime, it becomes very difficult not to do it again (and again). In some cases, the rewards of the crime tempts you to do it again. In other cases, the collaborators in your crime push you or blackmail you into commiting the crime again, because they now have incriminating proof against you. In any case, after the first crime, the power of conscience and the fear factor do not deter you any more.
Moreover, once you commit a small crime, it's likely that the gravity of your crimes will go on increasing.
