A very good friend of mine recently went to prison for 5 years. He was drunk, and so was the driver of the other car. The teenage passenger in the other car was killed. The driver of that car did run a stop sign, but my friend is still doing the time because he was drunk.
It definitely isn't worth it.
He did get sober after the accident and is still sober today, but he has tremendous guilt over the boy he killed.
