In my opinion, Abby from TLOU 2. During the first part of the game, she is portrayed as the bad girl, but when she become the playable character, you understand that she isn't:
-Her father and friends were unnecessarly killed.
-She became pariah from her clan when she saved a member of a rival clan.
-She have been harschly tortured.
-She spared Ellie despite having occasions to kill her for understandable reasons.
I don't get why many players didn't changed their minds at the second part of the game, it's so obvious that the real bad people are Ellie and Joël. Theres no problem about having sympathy for bad guys, but you must keep your critical mind.
And what infuriates me is that people even harassed the voice actress because of what her character did. Come on, guys !
Agree, the job is pretty merciless. People hate you whatever you do and even the most unsignificant of your mistake is used against you. If you became politician by idealism, you discover rapidly that persons involved makes you actually powerless: rival politicians, highly influencial ploutocrats, the supreme court (or equivalent), etc.
I have this impression with the US president. Despite the prestige of his position, he is actually highly powerless: most of the domains are in the hands of state governors, and if the supreme court, the senate and the house are not in his camp, he can barely do anything. It can be hard if you are really willing to apply what you promised but not being able to do so.
