"the guy deserved it" should never be justification for a state to kill someone. Even if you think capital punishment is justified, it should only be after a fair trial. And, if someone has a capital punishment sentence against them, that's only valid within their own borders.

If you violate a country's monopoly of the use of force within their own borders, that's a step on the path to war.

When the US demanded that the Taliban govt in Afghanistan hand over Bin Laden after 9/11, they refused, saying that the US should follow due process. They said the US should first submit evidence to their Sharia courts. The US responded by invading the country, ousting the Taliban and replacing their govt with one of its own choosing, and bombing and occupying the place for 20 years (the longest war in American history.)
