Honestly in a way that kind of thing kind of ruins any chance of trusting the guy, mostly bc you can’t trust him not to completely nuke the campaign bc he’s being an utter dick (which by the sound of it he totally did). The first time someone starts shit for fun, how do you know they won’t do it again every other time you hang out with them? Now you just have to assume they’re a bitter and immature enough person to always think that it’s fun to shit on everyone else’s day.
