Fighting against Lust can be very distracting for heroes. They'll be hard-pressed to control their basic instincts and avoid sinking into perversion. Proximity to their fellow team members will be a temptation too great to resist. When the Lust Sin is in play, if a hero ends their turn in the same space as another hero, they both take one Corruption. What takes place there is left to the imagination...
The Lust Sin cards explore this even more, punishing heroes that don't isolate themselves. Those Sin cards do things like granting extra dice to monsters attacking heroes in a group, luring heroes towards Lust monsters, or debilitating heroes who are even adjacent to other heroes.
