True, But

That's true that life isn't fair. But the difference between someone stuck in a wheelchair and someone that's attacked by another person is that the attackers can choose not to commit the crime against another individual. Where as someone that's in a wheelchair may have been born that way, or had an accident, or gotten a disease, or whatever else. No person intended to hurt that person, it just happened. A human being attacking another human being has the free will to decide to attack or not attack. They choose to do right or to do wrong.
