Any time my child hurt someone or put someone in danger I dealt with that severely. My son had extreme anger issues & sometimes destroyed expensive property, including a laptop & my phone, the way I dealt with that was taking the damages out of his allowance, gifts or whatever $ he had.

Disrespect (of anyone or thing) and lying are the most severely punished in our house.  

Jonbonjovious, my son was in therapy from 5 yr old. He was diagnosed with among other things: bipolar, ADD, ODD, but I don't think we ever nailed it. He was put on Ritelin, Wellbutrin, Risperidol. At one point he was taking 1000 mg of stuff a day, but it never seemed to help. Finally, I don't know if you call it a miracle or what, but at around 20 something when he started attending church again he seems to have conquered the behavior issues. Sending him to Job Corps helped too, it taught him discipline or else. At 18 he was on his own, I couldn't deal with the violence anymore.

Thanx guys! Yeah, I really do believe in the power of prayer. It might have even saved my son's life. He's a strong Christian now & I think he's developed very strong morals.

Lying for me is by far the worst offense. Trust is everything and once I see that there has been a lie or an omittance of the truth it really disappoints and upsets me!

I would also agree with lying. 

Yes, lying is a big deal to us, too. Luckily our girls are young enough that we haven't had much trouble from them. The time I was the most mad at my oldest it was because she was eating toothpaste - she was 4. Ha!
