They need those that roll with them to constantly express love for the organization and purpose, because without that love gangstas are unpredictable. There are two types of gangstas, those with specific goals, and those that are suicidal. If a gangsta does not see an immediate purpose for his life, then his life is not necessarily valued. Gangstas with goals value only accomplishing those goals. Gangstas without goals value nothing.
Gangstas see the weak as prey.
Either their prey, or possible prey for their enemies. Thugs hate sugar coating, plush lies, and fear. They desire to see and know the world as it is and express it as such. Thugs constantly harden themselves against fear, foolish love, and other characteristics of the prey they see around them. We need to unite those with goals, and those without goals must be given things to live for.
