[DC] Did Batman ever find closure with the murder of his parents?

Also is Batman considered insane?

Batman is a fucking lunatic. He runs around at night dressed like a bat punching people in the face. 

Insanity has been defined as repeating the same action and expecting different results. How many times do you have to lock Joker in the same asylum he has escaped from hundreds of times? How many times does Joker have to go on a murderous rampage before Batman tries something different?

Edit: To answer your initial question, no he hasn't gotten over it AT ALL. It's definitely his biggest weakness. It has definitely been used against him often.
