Dean told Sam in the promo that he had no right to feel sorry for Charlie's death. Is Dean right? So how much can Sam be held responsible? Is this the same as Kevin?
Sam told Charlie every step of his plan. He never lied and he didn't withhold any information. Yes he begged and used every form of manipulation he could think of but he also brought Cas in for protection. Dean kept Kevin in the dark about the potential danger in the bunker. The only life Dean thought was in danger was Sam. He couldn't have guessed that Kevin was a target. Are either to blame for the innocents that get lost in their quest to save each other or is it Winchester Business as usual. Anyone have an opinion?
