That was one my of excuses to the theme, perspectives; are you a conqueror or a peaceful explorer? It's possible to win the game without killing a single enemy.
There's more than one boss, and one of them is involved in a quest.
Interestingly, I caught on to the perspectives theme in another manner... namely, the way you worded your "Abort" confirmation dialogue. And yes, I've done plenty of aborts: good thing I can always just go get another one to retrieve the dumped cargo!
