I think, for the overall saga, he needed to die. HOWEVER, the way he died sucked! No way OB1 could be 10 or so feet below Maul, flip about 5 or so feet ABOVE him, land on his feet, then slice Maul without Maul even moving his lightsabre! Ridiculous! As fast as Maul was, there's no way that should have happened! I'm not saying OB1 couldn't have ultimately defeated Maul, it just sucked! Ok, that's my 2 cents worth.
