Dean, do we really have to shoot him ?

The most improbable Spn crossover ever. Sam and Dean are tough guys but even tough guys who hunt monsters 24/7 can have a heart and doubts about their mission. I can understand : If you were a hunter, would you kill Totoro ? I mean come on : TOTORO!!!! Ok, he's strange, he has a giant leaf on his head and he looks like he's high on drug but still...He remains absolutely adorable.
