Not really, there is a lot of this around. 40k is bad for it in games. people see 40k and decide that a character doesn't need human facets because kill kill bang bang grimderp. The essential makings of a good character don't change by the setting. Theres no problem with chars being dicks or wrong but a constant back and forth of "no my way is most righteous" is the kind of thing i think most people get enough of in real life without making it a thing between in game team members.
