Scott Pilgrim is a psychopath

I picked up the Scott Pilgrim books about a month ago and have now read through them several times. They're really good! They're super fun and are big on the gaming references, so you know I like them.

For anybody not following the series, the basic summary is that 24-year-old Scott Pilgrim (of the frigid Canadian north) is in love with the mysterious Ramona Flowers, but they can only date so long as he defeats her seven evil exes. It's all very lighthearted and fun, but something's been bothering me:

Why doesn't anybody care that Scott Pilgrim is killing a whole bunch of people?

He's seriously up to serial killer levels right now and not only does he show no remorse, but nobody else seems to care. It gets even more disturbing in Book 4, when we see Ramona hanging out with Roxie, one of her exes, and is even worried that she might be hurt when she falls off a balcony. Yet, not five pages later, Scott's chopped Roxie in half (and she explodes into a pile of bunnies.)

I get that it's all done in a comedic fashion, but it's still kind of unsettling. Everybody seems pretty okay with all these hipster kids killing each other. It's like some sort of weird spin-off of Battle Royal or something.

Regardless, I'm super-psyched and really looking forward to both the last volume (Scott Pilgrim's Finest Hour) and the upcoming movie. They're going to be awesome.

How do I know?

C'mon. It's Scott Pilgrim.
