I agree to straighten it. That piece is attached and is a part of the front fender. The metal is very soft and easily coaxed back into place. If you can get behind it with a dolly you should be able to tap it from the outside while pushing it out. When you get it where you want it paint it with a 1" brush with matching paint mixed for you at the automotove paint store in a pint can. Its down low so nobody will notice the paint brush lines. Take your time and use minimal impacts to avoid stretching the metal too much.
