Answer:
Strain Theory
Explanation:
The Strain Theory is a psychological theory that provides an explanation of the reasons why people engage in crime. Mostly because the society puts financial pressure on individuals, they tend to engage in crime. The general strain theory provides an even more encompassing explanation as it also attributes non-material intentions as the motivation for the crime. It explains that factors such as one's difficulty in realizing his goals, or even the lack of positive motivation could lead to crime.
