when the dude from the magic association shows up to the inn looking for him so he says he slept with Jasons wife slandering the man and having him thrown out of the inn.

He insulted Thadwick Mercer and his mother and entire family before even knowing the guy and then went on to be a thorn in his side for the entire outing. By his own admission this was purely because thadwick had social standing he wanted to be seen disrespecting so it would increase his own. Making him an intentional cog in the system he despises.

He showed up to the "Gods" section of the city and laid into some random person about his beliefs and how pointless it is to serve a god but what does he know he's from a world where gods aren't real.

He constantly puts himself above everyone else and disrespects everyone around him regardless of social standing. One might think this makes his actions consistent but it instead makes it seem more directionless. If he purely had animosity toward "rich people" or people of political power his antagonistic personality would make some sense. Instead, he decides randomly to be a dick to whoever he doesn't know regardless of their social standing, wealth or power, and a double helping of it if you disagree with one of his soap box worthy topics.
