There's definitely folks that take all they can get, scream about unnecessary things, and are just general drama, but overall are basically an underperforming IC. (I've even seen one become "best friends" with a director which caused all sorts of chaos and disorganization in the org below them, with the director blissfully unaware because the toxic person was giving side-channel status update to the director outside of the org hierarchy.)
Neutralizing them by giving them unimportant tasks often enables them to be louder elsewhere.
There's also people who are loud because they're trying to make the company better. They'll make you uncomfortable as a manager, and they'll make you have uncomfortable conversations with your leadership. They're...probably the ones to listen to.
True leadership is knowing who to keep close—even if uncomfortable—and who to rapidly manage out.
A good manager can root cause these issues and then determine if the resolution is workable in a reasonable timeframe. A great manager keeps this in mind while coordinating all activities and requires their direct reports to assist them in doing this.
Finally, great leaders are sometimes not great managers. Another note - even managers can shift from good/great/bad over time.
Worse, they make the organization toxic for everybody else.
I've come to believe the most important job of a manager is to quickly identify these people and either fire them or neutralize them (i.e. put them in a closet and assign them a meaningless task).
This requires a culture shift in most organizations to understand that toxic people (e.g. bullies, narcissists, and those with other serious personality disorders) have an outsize negative impact on productivity and profits and can kill the company if you don't get rid of them quickly.
