It's so easy for humans to believe that they've actually destroyed something.
You believe that in order to really destroy something, you have to know it; you have to understand it.
You have to make the act of destruction graceful enough so that the original form and the new form somehow still co-exist.
It's like a change of bodies.
The purpose of this, of course, is to create tension in the mind's of those who observe this change. And, in your mind, you feel absolute power.
