You and your allies stop them.

99.9% of humans are normally cooperative with other humans.

The .1% (or less) of humans that are sycophants are born leaders that are very hard to stop.
These people become politicians and are able to protect themselves and at the same time attack others all within the laws that they create.
Governments are fictional entities...a sword and shield for wicked leaders.
How much damage can they do, and for how long... in the absence of government protection?
