I was thinkin- maybe heavily karma-based encounters should have a red/green color to indicate what the choice may do to your karma? Of course, as to keep the 1K option to show karma worth it- it doesn't say how much Karma you would gain/lose, just a general idea of what it would do! :0

Or! The 1k option to show what an encounter does to your karma could perhaps show what it'll do before you click it (like near the option)? I don't know if it'd be difficult to find a way for this option to work without crowding the explore bar though ^^''
