Your constitution is not the epitome of justice or democratic ideals, and is in fact deeply flawed on a fundamental level.
I can accept that it has flaws, but on the fundamental level? It seems pretty solid at that level. The creators thought through the problems and difficulties of government more deeply than most.
Most modern constitutions also need all the procedures, of course, but they put certain "inalienable rights" square in the middle of it all. The procedures are merely there to support those rights.
Different times, different mindset.
Hilariously ironic how things turned out instead.
But seriously, murder being bad is pretty much a human moral universal. You'll find that basic idea wherever and whenever you look (+/- various caveats).
