More along the lines of "Maybe you should try to look for solutions that don't involve harming others who had nothing to do with it." Kirk's trying not to encourage Deela to continue doing what she did to them. It's another bluff. She's darn fortunate a Federation Starfleet ship happened upon them and not somebody with fewer scruples about what constitutes an acceptable response to the incident. Note that Kirk doesn't answer her question. He lets her think what she does for now. But he does recognize that they ought to have help, and if significant help was offered, they wouldn't feel the need to resort to such tactics. With the water having an antidote, Federation scientists can, in order to interact with the Scalosians in "real time", drink it and be very careful, then take the antidote afterwards. Or they can just communicate in a series of delayed messages. Any samples needed can be taken by the Scalosians and left for the doctors to analyze.
