The idea that all human life holds equal value is the most ridiculous and damaging viewpoints held by the ignorant idiot masses.
If we are looking for socially optimal outcomes, the lives of genetically superior individuals (more intelligent, more hard-working, more entrepreneurial, less violent, less greedy... etc) are worth far more than those without these characteristics, since these are the people who are the engine of growth and civilization.
Frankly, unintelligent people and criminals should be shot or at least sterilised for the good of humanity.
