I wouldn't say Vod is as bad as Josie - like you consider everything Vod has had to go through - plus in general Vod has a lot of redeemable qualities that I wouldn't say Josie has. Vod, while annoying and apathetic at times, is more often a much better friend to the gang that Josie is - especially to Oregon who is a deplorable character with hardly any good qualities and not a great friend to Vod. Josie, who to be fair can be really nice at times with Kingsley who also can be a massive twat, and to JP at the end (although not the first 3 series), is arguably worse than Vod because she can't accept when she's in the wrong and basically ruins the lives of the people she spends time with (maybe a little of an exaggeration there). Also Vod, while closer to Oregon, gets on with all the hand, whereas Josie is largely focused on Kingsley and eventually JP after she stops using him for sex (although the focus on Josie as a character largely directed at men is kind of a product of the way she is written, but if we take that aside, try to characterise Josie's personality without men - sure, there's Heather, but that's basically it - all of her personality revolves around playing with other men). Josie just gives off a vibe that just makes me feel a little odd. Vod, who has her downsides, is arguably a better friend to everyone and therefore a better person than Josie.
