for me, as long as it's profitable for both sides of the trade, it doesn't matter. Trading is looking for profit regardless of who we trade with.
of course but there are certain limits or deceny that makes you or a human being or a savage/barbarian... for example trading in captive sex slaves (even children) is savage/barbarians or endangered last few remaining of a species, or buying medias/regulatory capture to hide your outsourcing of your waste (toxic) in the ecosystems...
that's where regulatory authorities take their power, but from MP (market participants) and not some self proclaimed arbitrators or judges... one good sinful trading laws, was trading "god"coinns (fake) on the temple mount in yerushaleim 2000years + ago by some corrupt deviant wicked unlawful fake jews and their backers in the arbitral crews...
or for example if talibans say no pork meat trading on their meat floors, so be it, how is the lamb? clean gmo free, ground feed, unvaxxed, unhormonized, happy sheep life? all yes... hmmm !!!
