There was a topic before about whether or not Scar was responsible for the drought that hit the Pride Lands during his reign. While I do think that in the TLK universe he was indeed the one that caused it, as per the Fisher King, and I do encourage people to continue to debate about whether he did or did not cause the drought, I thought of something as somewhat of a "sequel" to this idea:
Okay so the drought hit while Scar was king. Did he cause it or not? Doesn't matter so much now. What matters is what he does. In the movie, we saw how he carelessly ruled in favor of the hyenas if at all, and basically completely failed to try and avoid famine. This neglect of duty is what caused the lionesses to become angry at him and send Nala out to find help in the first place.
So in the previous topic and elsewhere, I did come across the opinion that perhaps Scar was treated unfairly. That he is considered a bad king because of bad timing and of having to rule during a drought, while as far as we are aware, Mufasa did not have to. By that extension, Scar had to deal with a much worse situation than Mufasa had to, and therefore it's not fair to place the label of "bad king" on Scar because of this.
I personally think that Scar was a bad king in this case because his most visible policy as king made what could have been a simple drought into a horrible situation: He overpopulated the Pride Lands with predators. By allowing in too many hyenas and forcing the lion pride to tolerate their presence, the predator-prey scale was thrown off balance and the natural balance of animals shifted too far away from the equilibrium point.
When the drought hit, Scar had two binary options to chose from: He can go against the hyenas and at least force some to leave (or have the lions leave), or as we saw, he could not do anything. He shoved the problem under the metaphorical rug until it was too late, and the lionesses had no other hope but to commit the ultimate betrayal and actively work to remove him from power. So yes, I do consider it fair to label Scar as a poor king, if not for causing the drought, for failing in acting properly when it hit.
What do you guys think?
