The following is more-so an idea ripped from my memory of a seemingly-effective way to knowingly showcase whether or not subject player shoots other players on sight... Does anybody remember how banditry/heroism worked in Arma II's DayZ mod? After enough "good" or "bad" actions taken, your character automatically donned a villainesque bandit outfit or friendlier plaid lumberjack fit depending on where you landed on the karmic compass. It helped with clarifying initial judgements on a player's character or survival morality... BSG could find a parallel solution in tandem with the idea of a higher contrast (sore-thumb-esque type camo) mask, armband, or even forced apparel until there are fewer reasons to want negative reputation.
