We do not have the death penalty in Canada, and generally speaking it is a good thing. But there needs to be an "exceptional clause" for mass murders.
We have a couple of terrible mass murderers in jail. Technically, life in Canada is 20 year, usually 10 years with time off for good behaviour. But the mass murderers have to have parole hearings, and then all the people who are involved have to travel to Ottawa to testify about how the murders of their children have affected them. So every year, the wounds are torn open for these poor parents. And then the parole gets turned down till next year. Scary stuff, if someone decided to let these particular people go! They have in no way repented, any of them, they are psychopaths. No conscience!
So we have to house and feed these people, when they should have been put away a long time ago. I think we are basically talking about 3 or 4 people maximum.
So I am not for the death penalty generally, but I think the state does have the right to intervene in special circumstances!
