Power and need for control are strong motivating forces for evil. Which character in The Mockingjay displays this most predominately?Power or a...

There are many characters in Mockingjay by Suzanne Collins who
are have a need for control and power.

The character that
predominantly fits this role in all three of the books is President Snow. In Mockingjay, Snow
uses Peeta to control Katniss as well as the Rebels. Snow is a character who needs power and uses
it to control the districts. He abuses that power by oppressing the outside districts, supporting
the Hunger Games and lavishing the Capitol with food and luxuries to keep them appeased
too.

You could look at Gale as a character who misuses power or
plots to misuse power by developing weapons that will kill innocent people. This character study
would be best done if you look most closely at the part where he is developing weapons with
Beetee as well as when they are taking over the Nut in District
Two.

Coin would be an interesting character study and look at why
Katniss refuses to follow either Coin or Snow in the end of the novel. What is her purpose in
using Katniss for the propos throughout the novel? Why does Coin send Peeta into the war with
Katniss?

I think Katniss mostly works against wanting and needing
power because she recognizes that it is an evil motivating source as you call it. She is not
someone motivated by evil though.
