The reason that most criminals become and remain criminals is that they are not actually willing to put in the effort to work hard and earn anything the legitimate and honest way. The norm is that most criminals do not have a very good moral character nor stable foundation or family from which they come. Generally due to an extreme lack of bravery, criminals will take things the easiest way possible, exploiting and taking advantage of people just like you, without any care for your health, commitments, family, employment or resposibilities. This is why they are criminals.

Violent criminals tend to attack those who they perceive as weak or vulnerable in some way. When criminals feel that they have an advantage in size, location or number, they use this opportunity to victimize others. Thus, they look for the "Easy Mark". Consequently, they don't tend to think of defense. This leaves them open for decisive countermeasures - IF one has the will to act.
