I can't even decide which one I hate more. LF, I think, but Varys is close

this reminds me that i noticed yesterday no one had opted to discuss these two pivotal characters in the discussion post. i was hoping someone would because i would love to understand them better. well, at least varys. i feel like i know what and why littlefinger is but what is varys' real motive? is it just to put aegon on the throne and if so, couldn't he have accomplished it differently?

i have so many questions!
