I agree with everything the other posters said, but it might all be self-sabotaging behaviour: both breaking the law and the rest. Any comments by you to "remind him" may work counterproductive. Panic/anxiety is generally about some underlying problem one cannot properly express or rationalise. It's best to talk about any underlying problem, which could be sabotaging himself, and speak about why he does it. The reason could very well be an inability to talk about and rationalise an even further underlying problem: his BP. He might just unwittingly do these things to give an "rational" explanation for his troubles by clearly hurting himself, again, just so as to have a "valid" reason.

Such self-harming behaviour is quite typical. One could argue that the risk-taking by those with BP (especially when manic) is for a considerable part to have an valid reason for failure, leading to a relatively milder depression (the rest being accounted for by the strengthening of mania by limiting options and consequent stress/excitement).

But it could be something else completely, of course.
