On the one hand I don't really disagree. I can't generate much concern for what happens to these two.
Though that's partly because I can't help but mentally lump them in with the larger group of "motorists who get away with killing vulnerable road-users" (a topic I have an existing anger about, because there are so many cases of that happening), so there's a bit of collective-punishment in my own reaction that I'm not sure is fair.
But on the other hand I still think the far more important issue is 'what produces people who behave like this?' and 'how do we stop creating such people...or at least make it harder for them to do such things?'
Whatever happens to these two individuals it isn't going to really fix anything.
I'm of the opinion that some people are just going to be scum. Doesn't matter how they're brought up, they're just going to be scum of the earth.
It's a very complicated issue, but just generalizing here, I'd say being raised in a nurturing environment plays a huge role in kids growing up to be good citizens.
Workers need to be paid a thriving wage, not just a living wage, but a thriving wage. A thriving wage is one where you have the ability to pay for housing, food on the table, and still have a little money left over for entertainment and a real vacation away from home every couple years. There's no reason a CEO makes more in one day, than the majority of a company's workers do in a year.
Housing can't just be a place to sleep. Recreational facilities such as a basketball court, swimming pool, and other areas where they be physically active. People need access places to socialize, a place to just sit and enjoy nature if that's what they wish, or one to play board games or other activities with friends and family.
Access to higher education. THERE IS NO DOWNSIDE TO SOCIETY WHEN THE GENERAL POPULACE IS EDUCATED. The only downside is it's harder to suppress the plebs if they're educated. The upside is you have more citizens studying fields such as maths, sciences, and other fields. You'll also have more citizens taking up art, such as writing music, books, and poetry. As an avid reader, I'd love for there to be more literature for all.
Equality for all. Women and minorities are people too. You cannot expect to suppress a group of people based on things like color of skin. Everyone deserves the right to their own bodies, and to express themselves as they wish. Yes, this means you can't use religious reasons to do things like ban abortion, or force any one religion upon your neighbors.
