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 !
