It doesn't end because, you'll have people come in here talking about they are children and their whole life in front of them and they shouldn't be tried as adults and they are blah blah blah.........instead of saying kill them and make an example. Is that too harsh...no, no harsher than the sentence carried out by their actions against some poor unwilling person.
I'm sorry, it's no different than a good kid in all aspects of life who gets drunk, goes too fast, wrecks, and dies. It's sad, tragic, terrible, but, completely unavoidable. Bad choices have consequences.
You know why you don't put your hand on the hot burner on the stove........yep, because it's hot, only takes one time to do it and you'll never do it again.
When people start to understand that some choices you make allow for no second chances and ultimately, end your life, they begin to think and view things differently. Especially when it has finality, no appeals, no other outs, just one unavoidable consequence.
