So far, I've only heard of nation-states committing atrocities whose gov't officials end up in the Hague...
How about companies, whose CEOs and stockholders have a role in committing such large scale crimes who deserve the wall?
Edit: Bonus points if you include a death toll...
From what I've read on wikipedia's Nestle
In a 2018 study, the National Bureau of Economic Research (NBER) estimated that 10,870,000 infants had died between 1960 and 2015 as a result of Nestlé baby formula used by "mothers in [low and middle-income countries] without clean water sources", with deaths peaking at 212,000 in 1981.[47]
Nestle knowingly lied to women about formula being better than breast milk when they did not have access to adequate amounts of clean water in part because NESTLE OWNED ALL THE WATER.
Nestle also uses child slave labor in their chocolate supply chains and uses paramilitary death squads to suppress workers attempts to organize (as does coca cola and many other corporations that operate extractive industries in the global south).
