The only players who should feel REALLY guilty about Magincia are the ones who screamed at people for actually trying to save the city by killing light demons. Honestly, it was a very unfriendly scene there at times.

I got quite a bit of flak as well, since I kept dragging demons out to the woods to "pop" plant rubble. There was a small but distressingly unpleasant group of people who seemed to regard every light demon as theirs, to do with as they pleased, and anyone who got in their way was either harangued or messed with.
It's like Magincia didn't fall to pride so much as it did to brattiness.
