its obi-wans fault!!
ok, as i see it, qui-gons death was obi-wans fault...i wouldnt be saying this unless i had a good reason either...i watched SW Ep.I again the other day cause i was bored, and at the end when they were fighting darth maul together obi-wan had the chance to kill him a couple of times, but wat did he do? nothing! but i kno, he was really upset that qui-gon was killed, and i feel bad for him(ok..do i have a fever?i usually hate obi-wan) but if he really wanted to he could have killed darth maul earlier and qui-gon wouldnt have died, unfortunatly for him and us, he didnt think, therefore he didnt take the chance to kill darth maul, and as a result to that, qui-gon was killed...
