There was a programmer at my job, he put out the vibe of being a gung-ho guy and got promoted to team lead. The moment he had a scrap of power he started publicly berating the other devs, randomly, over nothing, leaving me wondering who he’d snap on on a given day. One day I got the message to shut off his access to the build server, which meant he was fired. It took way too long but it was delicious when it happened and my work satisfaction skyrocketed. An asshole can change a whole job.
