Karma is a hidden parameter in Escape from Tarkov.
The karma value changes depending on the player's actions. Generally, it can be increased by adhering to a more "open" play style, and decreased for a "dishonest" play style. According to the patch notes of patch 0.15.0.0, Partisan is more likely to appear in raids with low karma PMCs and will hunt them down. If there are Scavs with low karma (not Scav karma) appearing in a raid he is in, they will also become his targets.
