Covertly recruiting a person on another team to start a small project that was in direct opposition to a project my team had planned to start on in a few months and aligned with all relevant stakeholders. He …disagreed… with it so his solution was to make this other thing happen and then there would be no room for our project when we were going to start.

Yes, there was liuqid hellfire when we found out. He kept his position as CTO for a few more years. Eventually he pissed off his own boss too many times and got fired very hard.
