Another ‘what if?’

Here’s another thought provoking ‘what if?’ from hunger-games-what-ifs on tumblr.  So what if the District 3 boy had not allowed himself to be used by the Careers, but instead used the mines to his advantage?  What could he have done?  He certainly could have prevented the Careers from creating that booby trap around the supplies, although this would have hindered Katniss’ ability to destroy those supplies.  Could he have taken the detonated mines and reactivated them in the woods to take out as many tributes in there as possible? Or maybe even used them as a security system, securing himself in an area with the active mines strategically placed around him so any would be killer would be blown up?  Do you think his fate would have been much different had he not sided with the Careers?
