"Men are so simple and so much inclined to obey immediate needs that a deceiver will never lack victims for his deceptions"

In this quote, Machiavelli suggests that guys are quickly swayed by their immediate desires and requirements, making them susceptible to deception. A manipulator or deceiver will always find people to victimize because of their simple and short-sighted nature. Essentially, Machiavelli is highlighting how susceptible human nature can be to deceit and adjustment.
