"Why is there such a high value placed on human life that ignores the impact that person had upon the world?" This is the wrong question. There isn't a high value on human life, the leaders are permitted to execute and kill people. There is an incentive for people in power to not want to create a precedent for the killing of people in power, for obvious reasons of self interest. There's also a precedent for people to live vicariously through leaders, be they a political leader or someone like Elon Musk, which can presumably lead to violence if you make them a martyr.
