I have to disagree - these people are empowered because they were immune to the consequences of their actions. This would show you're not immune, that your choices and actions have consequences from those you are making suffer, and that the world doesn't exist in your ivory tower or group think.
The next fascist leader would go in knowing exactly what happened to the predecessor, exactly what the people think, and that they won't take your actions lying down.
You're delusional if you think a killed Trump would have been good. He'd get replaced by a more evil and intelligent republican which would then definitely win the election.
