It is really hard picking someone to truly hate.
I hate periods that people are in, especially Captain Kimmet, but the same I can kind of understand where they are coming from and enjoy watching their growth out of it. Thats what makes this podcast so awesome! So many flawed characters that have reasons behind their flaws.

But I will go with Captain Kimmet because he refused the chance to evolve, forever stuck in the void of believing he was right and the hero for everything.
