I've always felt conflicted about drunk drivers. On one hand, when thinking of it rationally, I do believe that more often than not it's someone who is making a huge mistake, rather than being a bad person at heart.
Then again, when anything of this sort happens, I can't help but feel immense amount of anger about how one can so selfishly put the lives of other in danger. Although I've never had issues with alcohol myself, it's a touchy subject because of certain family members, so I'm probably unable to really think of it subjectively.
In any case, rest in peace Johnny and Matthew Gaudreau, and may their families find some peace.
