Disabled script works anyway

I have a simple code that will be enabled when I kick, so I disable it right away but even though it is disabled, it works somehow. can it be because of his parent or something else I dont know of?

//this is the script Kick_Test, i dont reach it from anywhere else
private GameObject ball;
private Rigidbody2D rg2d;
public int power = 30;

void Start()
{
    ball = GameObject.FindGameObjectWithTag("Ball");
    rg2d = ball.GetComponent<Rigidbody2D>();
    this.enabled = false;
}

private void OnTriggerEnter2D(Collider2D col)
{
    if(col.tag == "Ball")
    {
        Debug.Log("KİCK");
        Vector2 pos = (transform.position - col.gameObject.transform.position).normalized;
        rg2d.AddForce(-pos * power, ForceMode2D.Impulse);
    }
}
