Thought Patterns and Actions.

Distorted thinking phase: The subject is unable to properly assess the impact of a deviant act, as he fails to consider the consequences and is more interested in the emotional gratification that can result from his actions.

Motivational phase: The stimulus is perceived as something personal and the distorted mentality of the subject produces a disproportionate response to incidents.

Inner negative answer phase: at this point the murderer has to deal with feelings of inadequacy, especially when there are negative messages from the society that surrounds him.
