the.com/terrorist

means Someone who uses violence or the threat of it against civilians to spread fear for political, religious, or ideological ends.

from From French 'terroriste,' coined during the Reign of Terror in revolutionary France — originally describing the Jacobin agents of the state's own terror campaign, not outsiders attacking it. The word pivoted within decades to mean those who use terror against governments rather than for them, a flip in direction it's never really stopped making since.
