Pisces Threats

One pisces has been pursuing my gemini friend since high school and gets violent whenever she try to skip away from him. He threatens her. Started drinking on a large scale and got some liver damage. and again threatend that he will take drugs and sstarted on it now. Keeps threatening her saying he will die like this if she wont agree to marry him.

Is this some unique dumb pisces or is it some general trait whcih most pisces men sucessfully overcome??

Let him die. Problem will solve by itself.
