Yea, not having to work with assholes is pretty great. Maybe there is some tradeoff to be made and a balance where keeping a productive asshole around could be better for the product than purging said assholes, but I think a team with that toxicity can't be sustainable in the long run unless its a team full of assholes that are content.

Don't let the world see you dirty laundry. Every company has these problem, customers should never see it.
