Truthfully, yes.
That's not to say I would not show all the usual emotions victims & their families display.
Of course, we don't have Capital Punishment in the UK any more, but if we pretend for a moment we have, and that was my daughter, and the perpetrators of the crime were sentenced to death, I would still like to think I would strongly oppose it. For several reasons, the main two of which are below.
1. An eye for an eye does not right wrongs.
2. You would have to be absolutely certain beyond all reasonable doubt that you had the right person.
Look how many have been put to death in the US and subsequently have been proven innocent. Then there are those who are genuinely insane or otherwise not culpable. Add to that list the countless juveniles who have been executed and that is a strong case against the death penalty.
