I get where you’re coming from, but to me the problem with saying that it wasn’t intentional is that when you drink and drive, you do so knowing, accepting and being okay with the fact that there’s a very real chance you’re going to kill someone in the process. So while he may not have intentionally been trying to kill anybody, he certainly wasn’t too bothered by the idea of it either. If he was, then he wouldn’t have been drinking and driving in the first place. Instead, he decided to place a higher value on his own selfish desires than the lives of innocent people. That’s a sick, disturbing mentality and it needs to be punished accordingly.
