Walter once bubbled...
Human life must be held in very high regard and we should all be sorry when it is lost. This man got what he deserved only in the sense that all actions have consequences. The consequences of his actions was his own death. We cannot protect people from their own stupidity, but rejoicing at their deaths is wrong. This person probably deserved punishment for beating the dog (assuming we do actually have all the facts which is not likely), but that punishment would not have been nor should it have been death.
Very well said Walter. I agree fully with the quoted statements.
