This has been bugging me a little bit here about Boxcars, as he asks for Med-X to OD himself, which also gives good karma while at it. However, wouldn't it be more rational/logical to have an option to offer him Stimpaks, so that he could heal his crippled legs? Or Doctor's Bag even, for that matter? Hell, and why give good karma and not instead Powder Ganger reputation, as you are clearly helping a convict here that wouldn't be goody-two-shoes. Hell, this raises a point even at the Bitter Springs quest, where you'll have to clean some irradiated medical supplies. You use Rad-X, instead Radaway, but wouldn't it be much more convenient to use one that is liquid, instead of smashed pills?
