to collect the data. There were four theories to support the analysis of the study. The theories were prejudice, discrimination, violence, and typology of violence.
B.        Review of Related Theories
This  part  reviews  the  theories  which  are  employed  in  the  study.  There are some theories that will  be used to  solve the  problems  formulation. They  are
the theory of motivation, personality, character, and psychological approach.
1. Theory of Motivation
Maslow 1954 states that motivation is the human ‟s action that is driven
by  a  need  to  fulfill  in  order  to  achieve  a  higher  purpose  of  life  called self-actualization  p.301.  He  assumes  human  as  a  animal  that  wants  to  prey
others  for his  satisfaction. When a person satisfies  this  one, still another clamor for  satisfaction.  It  is  the  characteristic  of  human  life  that  people  almost  always
desire  something.  Maslow  divides  the  motivation  into  five  stages,  which  are physiological, safety, social, esteem, and self-actualization.
Maslow  describes  human  needs  in  the  shape  of  hierarchical  diagram.  In this manner, Maslow
‟s model indicates that fundamental, lower-order needs like safety  and  physiological  requirements  have  to  be  satisfied  in  order  to  pursue
higher-level motivators along the lines of self-fulfilment. In Maslow ‟s diagram; or
sometimes called Maslow ‟s needs pyramid; lower factor needs must be satisfied
before continuing to satisfy the higher needs. Here is the diagram of five stages of motivation from Maslow:

Figure 2.1 Maslow’s five stages of motivation
a. Physiological needs The  physiological  needs  are  the  most  basic  human  needs  to  sustain  life  in  the
world. The needs are food, air, drink, and sleep. Maslow states that this need is the  basic  need  of  human  life,  if  these  needs  are  not  satisfied,  the  other  needs
cannot be achieved. b. Safety needs
After the physiological needs are satisfied, the next human needs is to secure,
in order to be free from the threat of physical and emotional harm
.  This  needs cover security, protection from danger and the freedom of pain.
c. Social needs These needs are related to the interaction with others such as friendship, giving
and receiving love, engaging in social activities and group membership. Maslow
also underlines t
hat the love covers “giving” and “receiving”.
