The Death Penalty For Acts Of Terror.

Of course, when I heard about the Boston atrocity, my first thought was that Massachusetts does not have a death penalty. My second was to wonder if this case would be prosecuted under federal law.
I was relieved to see that this would indeed be the case.
The do-gooding element would no doubt throw up hands in horror 'that a Christian could support such an abomination based on revenge.'
Before even attacked, I shall defend myself:
1) It is utterly immoral that any person should be permitted to  take the lives of others on a whim, by means of purest evil, without their own life ever being threatened.
2) Any penalty less than death for such a crime is effectively condoning the act.
3) Any penalty less than death, devalues those lives lost.
4) Retribution is called for. Retribution is neutral - revenge is personal. (Why does the figure of Justice wear a blindfold - we may reasonably ask?)
5) Righteousness depends on justice being fully accomplished.
6) Any penalty less than death shows weakness to both criminals and the terminally evil alike.
7) God demands action. 'He who sheds the blood of man - by man shall his blood be shed.' Gen: 9:6
8) Jesus Himself said that 'He had NOT come to abolish the Law.'
9) The USA shames the European Union which has removed even the possibility of vindication where acts of evil have been committed.
10) There really is no other reasonable or logical, moral position.
Long may the USA retain capital punishment.
