It was understandable. Lethabo mistaking Sango as the God Of Destruction because of the statue of the God Of Destruction that he has once seen is an understandable situation.
After all, the inspiration behind the statue of the God Of Destruction is originally taken from Sango's appearance.
When one sees the statue of the God Of Destruction once, and in the next moment, one looks at Sango. That person will be inclined to call the sango and the statue the same.
That is how uncanny his resemblance is to the statue of the God Of Destruction statue, though with only a few minor differences here and there.
As earlier said, it is indeed understandable in the case of Lethabo referring to Sango as the God Of Destruction.
But... There are certain cases where a mere coincidence is not what it turns out to be... Coincidence.
Within that coincidence, you can feel that there is more to it, more to the words spoken that led to the urgency of the coincidence.
