I injured my skin and apart of mole it bled then the blood dried and it peeld the skin and apart of the mole had a light Brown scar is it ok?

Usually ok. A mole won't alter the chances of an injury at that location. For example, if there is a knee mole, the person will scrape her knee doing sports, regardless if there is a mole there or not. A mole should also return to normal, but will be smaller for a while if a chunk of it got ripped away. If a healed mole keeps changing after injury, or is otherwise worrisome, one's dermatologist should check.
