Despite Aldnoah Zero being stupid as fuck I can't help but enjoy how the events have unfolded in Season 2. The first 3 episodes of S2 have sort of reminded me why I was so into the series during the first 3 episodes of S1. Yeah the characters and overlying conflict doesn't make a lick of sense within the context of what happened in S1 and Earth should have been fucked right to hell after the shit that happened in Russia but they've found a way to focus in on the aspects that made the show originally catch my eye. Hopefully there isn't another huge drop in quality like last time though.
Without going into detail, the answer to your original question is yes, he does get less asshole-ish over time.
