Can my player transform scale change OnCollisionEnter interactions

Hi,

I want my character to get killed on collision with an enemy if its under a certain scale (ex: <= 1, 1, 1) but to destroy said enemy if over a scale value. (ex: >1, 1, 1).

So far, my character gains size using the following script:

  if(collision.gameObject.tag == "Shrooms")
         {
             transform.localScale += new Vector3(0.6f, 0.6f, 0.6f); 
             Destroy(collision.gameObject);
         }

Now Id like for my character to destroy an enemy if over a scale but not to if under that scale. I started playing with stuff like this but it doesn't work so far:

 if(collision.gameObject.tag == "Enemy")
 {
     if(transform.localScale.sqrMagnitude >= size)
     {
         transform.localScale += new Vector3(0.6f, 0.6f, 0.6f);
         Destroy(collision.gameObject);
     }
 }

I'm just throwing this out there but Ill keep trying stuff on my side of things. Thanks to anyone answering.
