Curses were thought up by bored, lonely women way back when who knew how to tap into the primal fears of their tribes and did so because they were vindictive, lonely, aging women who had too much time on their hands.
Then a few simps followed them around, absorbed their thoughts, let their fear run wild, told some people, wrote some stuff and now people think rituals are anything more than voluntarily brainwashing yourself to give demons your power.
If you try and curse the wrong person not only will they not even know about it, it'll come flying right at your head at many times the force.
Why believe stupid things when you could instead believe in good things?
