my lose health script isn't working?

I am making a two player game (sort of like smash bros or gun mayhem ) it has two scripts that when one object enters the trigger collider it either destroys it if its a not a player or respawns if its a player and the player loses 1 health (that's what is supposed to happen but the player will sometimes lose 1 health and other times the other player will lose 2 health) here are the two scripts:

the health script:

     int curHealth = 5;
     public Text health;
     public GameObject me;
     public Text winText;
     public GameObject Green;
     public GameObject Red;
 
     void Start ()
     {
         winText.text = ("");
     }
 
     void Update ()
     {
         health.text = ("Health: " + curHealth);
 
         if (curHealth <= 0) {
             Invoke ("Death", 1);
             health.text = ("Dead");
             if (me == Red) {
                 winText.text = ("Green Wins!!");
                 Invoke ("NewScene", 1);
             }
 
             if (me == Green) {
                 winText.text = ("Red Wins!!");
                 Invoke ("NewScene", 1);
             }
         }
     }
 
     public void LosePoint () 
     {
         me.transform.position = new Vector3 (0, 3, 0);
         //gameObject.SetActive (true);
         curHealth -= 1;
     }
 
     void Death()
     {
         Destroy (gameObject);
     }
 
     public void NewScene ()
     {
         SceneManager.LoadScene(0);
     }

the trigger collider script:

     public Rigidbody2D rb;
     public HSpriteSystem hScript;
     public GameObject player;
 
     void Start()
     {
         
     }
 
     private void OnTriggerEnter2D (Collider2D other)
     {
         if (other.tag == "Untagged") {
             Destroy (other.gameObject);
         }
 
         if (other.tag == "Player") {
             hScript = other.GetComponent<HSpriteSystem> ();
             hScript.LosePoint ();
         }
     }

(the health script is called HSpriteSystem)

What's Going Wrong? How could I fix it?
