Should Capital Punishment Be Permitted?

In the 1995 Oklahoma city bombing, Timothy Mcveigh killed 168 people. Anyones first thought would be, he deserves the same fate. Killing all those people because he himself hated the government was ridiculous and insane. So the jury sentenced him to death. But was this really a fitting punishment? Yes I agree he deserved to die, as I'm sure many of the victims family agreed. But I think it would have been more reasonable to make him suffer and rot in prison then to simply let him just die, free of pain and suffering unlike his victims. A life sentence in a high security prison, without parole would have been a fitting punishment. Just like Mcveigh had no right to take all those lives, the government does not have the right to take any lives. I believe sentencing a killer to be killed is like giving them what they asked for and is not teaching them a lesson. If I was in his position I would rather die, then spend my entire life rotting in a jail cell.
