Hi
I think its a tough competition!
Mira cos she thinks she's the best
Handmaiden cos shes childish
Visas cos she's selfish (wanting the exile to stay with her)
Atris for just being a b*tch
Kreia cos she uses people to her own ends
Bastila cos she's always moody
Mission cos she can be snotty and childish
Juhani for falling to the dark sid ein the first place
Vash for dying instead of living!
Ooooooo i would have to pick, Atris, she gets on my....ah never mind lol
