Memory
Experience points (XP) are an abstraction used to pace out the party's combat skill progression in TSL. XP is typically given for quest progression and success in combat. When the Exile strengthens their connection with the Force, they gain XP, just as the Nameless One of PS:T does upon recalling their memories of past lives.
Because of the strength of genre convention around XP, it is odd for characters to notice that the Exile is granted XP for defeating worthy foes. Yet the Jedi Council describes this power as obviously horrific. They try to kill the Exile, or at least, prevent them from eating anyone else. It is the same power that Darth Nihilus learned, developed to the point where he can (and must) consume entire planets at a time. Kreia tells us the Exile discovered this power at Malachor, and the Sith merely learned from their example.
When asked to explain their motivation for gathering the Jedi Council - that is, pursuing the game's main questline, - the Exile can claim the Council stripped them of the Force. This prompt, however, arises before the player has any evidence to think this belief is incorrect. The player is then made complicit in failing to understand their own trauma, understanding it as a punishment which they could not possibly have inflicted on themselves.
Consequences of the protagonist's repressed past actions appear throughout the encounters in TSL, as in other games which encourage player-avatar identification through the amnesiac device. Disco Elysium (2019) is another example where the player character has left a dire mess behind, which must be reconstructed from the state of the world and what people are saying about it.
Spec Ops: The Line (2012), an FPS adaptation of Heart of Darkness (1899), explores war crimes in particular, just as TSL does. The physical degradation of the player character in both games reflects their failure to either emotionally process or seek escape from an ongoing cycle of death and terror.
