The first reason that Scar was the villain is because he was someone who was consumed by his own lawless desires, that he would do anything to achieve them. With that being said, even though Scar wanted an equal footing for all animals in the Pride Lands including the ousted hyenas, his actions were nothing but out of jealousy and anger. His own lawless desires brought him to the point where he commits murder on a member of his own family, Mufasa, the king of the Pride Lands. Killing his brother guarantees his heir to the throne since Simba, the king's son, is too little to take command. His desire was filled with jealousy and anger since Simba came into the world. In Mufasa's monarchy, Scar cannot inherit the throne because it is supposed to be his eldest son who steps up after his death. But if the eldest son is underage, it is the next brother in line until the son reaches the right age to take the throne. Knowing that, Scar gets little Simba to flee, making him grieve the death of his father and making him think that it was his fault that Mufasa had died. Having accomplished that, Scar knew that he would always be king and no one could challenge him anymore. This leads to the second reason why Scar is the true villain of The Lion King. The second reason why Scar can be seen as the villain is because of his deceitful nature. First and foremost, he misled Simba by making him believe that he killed his own father. Secondly, he was able to convince the hyenas to work with him in order to take over the Pride Lands. He had a deal done with Shenzi to eliminate Mufasa by using Simba as a bait to lead the king to his own demise. Eventually, this leads to an opening for Scar to set his footing on the throne. Scar gets Mufasa killed and then promises that the lions, hyenas, and all other animals will all be equal. When Simba returns, Scar and him have a fight for the throne and we quickly come to learn that Scar was trying to be the king only for his own needs and would not care for anyone else. Furthermore, Scar did not fulfill his promises and it looked like he never was going to anyways. The hyenas overhead his hideous words for blaming all his actions on them which made them realize how selfish and self serving he really was.
