If the spaceship blew up with the Newgrounds guys in it...does that mean I had a hand in killing them?
The spaceship blew up because some random guy decided to keyboard bash the control panel. The odds of finding the self-destruct sequence this way are 100%. In other words, no.
However you did set him free which led to this, so yes and no.
Also, if all we wanted from the Saracens (desert guys) was the map to the Flooded Temple and marsh, and we had to defeat some of them in a volleyball game to get it... then what the hell did we go around killing the snot out of them for?!?
