Respawn when a character hits an object with a tag of "Kill" , but after 3 deaths the controller is destroyed

I have tried to create some sort of death counter that counts the number of deaths and respawns the player after each death. After 3 deaths, the controller is meant to be destroyed, but i can never get this to work. Here is the teleporting script used so far:

 function Update() { }
 
     function OnControllerColliderHit(hit) {
         {
             if (hit.gameObject.tag == "Kill") {
     
                 transform.position = Vector3(0, 20, -36);
     
             }
         }
     }

this works, but when i try to incorporate a death counter, everything mucks up. Can someone please help me?
