For The Division 2, Ubisoft wants to offer really mean villains, which you will see in their voice acting and animations.
Real villains are what the fans of The Division desire, and this is exactly the wish the developers want to fulfill.

Real Villains in The Division 2
What is the problem? One of the criticisms of the first part of The Division was that the bad guys like the Cleaners did not seem really evil. They appeared more like waste collectors. The Rioters, for example, looked like regular civilians with baseball bats, which made them not particularly threatening. Ubisoft has already responded to this criticism, and the villains present themselves differently in the game today than they did at launch. Their voice acting has been changed, as have the animations, to make them appear even more sinister.
You can recognize the bad guys in The Division 2 just by their walk
Villains in The Division 2 are going to be even more evil. For The Division 2, the team plans to take this a step further. Villains will clearly be recognizable as such in the brutal world. Like the “True Sons,” which are brutes who bullied the weaker ones in school. Now they have access to weapons and begin to torment and torture people. They are supposed to really come across as villains, as scum representing the worst side of humanity. And this applies to all other enemies in the game as well.
The huge game world of The Division 2 will offer you real villains.
