Besides the context (and the legal aspect), they are the same act, homicide with intent. Their morality seem to be different depending who you ask.
And as for Libra being made illegal, I don't see what value it provides in EU to make it worth breaking the law.
Death penalty is not moral. How you got this out of my message is beyond me.
Killing enemy soldiers to defend your life or land is justifiable. They are trying to destroy you. But I guess this is weird from American point of view (I'm just assuming since I don't think anywhere else has death penalty still in use and other countries haven't been involved in war in foreign countries for past two decades), but killing people who don't look like you in their own land because they are firing at you because you have invaded them is actually immoral in more ways than one.
