GREEN LANTERN #3: A theory on Hal, Sinestro and Batman

[starwolf_oakley]

While reading GREEN LANTERN #3 I was thinking about Hal, Sinestro, and Batman. And then it hit me like a power ring construct of a giant green boxing glove:

Hal Jordan doesn't like Batman because Batman reminds him too much of Sinestro.

Any validity to this theory? Maybe Geoff Johns is just writing Sinestro to sound as Batman would at his most Batdickish.
