Maybe. But do you have an example of a society that do both death sentence and provide fair trial plus peers conviction?
Making prevailing the idea that some humans can reach a level of certainty that is high enough to put a death sentence on some people they didn’t even knew before that is telling a lot. Like, we humans never make errors, we don’t have any kind of cultural and idiosyncratic biases, we never have conflict of interest and we can’t be manipulated by miscellaneous social forces.
Murder is bad, and murder en masse committed through institutionalized legitimating mechanisms is thus extremely bad, as as many times as bad as how many people it kills.
Legal murder through institutions never prevented a society to have "random" citizen going awry and kill other people, but it never missed to add supplementary threats to all their citizen.
