Defining Criminality is difficult because it's a Social Construct;
What was once a Crime, may not be Now, and what is Crime Now, may not be in the Future;
It all depends on the people at that point in time.

1. Violent
2. Drug-related
3. Aqusitive
4. Sexual
5. Anti-social

Eysnerics's Theory on Criminal Personility along with Heaven's Study.
